Jo Shimoda will undergo an MRI this week after sustaining a lower-left leg injury in a multi-rider pileup at the sixth round of the St. Louis Supercross. The Honda HRC Progressive rider was removed from the track by the Alpinestars Mobile Medical Unit, was ruled out for the remainder of the night, did not start the LCQ, and scored zero points in St. Louis.

The crash began when Phoenix Honda rider Evan Ferry went down; Shimoda rolled a section and was clipped in the lower leg by Luke Clout in the first rhythm section, prompting a red flag, and he was seen favoring his left leg after the incident. Alpinestars’ initial on-site assessment found no broken bones but indicated possible ligament damage; Shimoda said Alpinestars medical told him there were no fractures. The MRI has been described as the decisive diagnostic step to confirm or rule out ligament issues and to inform any short-term treatment or recovery timeline, and the team has said its immediate focus is obtaining accurate imaging and a recovery plan that preserves Shimoda’s championship chances.

Team manager Lars Lindstrom said the injury initially looked serious but that he is “more hopeful that it’s only a minor setback,” noting Shimoda could put weight on the foot during initial checks and that putting weight on the foot seemed to be okay. Entering the round Shimoda trailed championship leader Cole Davies by 14 points; after scoring no points in St. Louis he now sits fourth in the 250SX East standings, 36 points behind Davies.

Eli Tomac’s recent dip in form and health has become a central story in the 450SX title race after a string of subdued outings. At a recent press day Tomac said, “Physically I’m fine. I’m good,” while also acknowledging he’d been “a little bit under the weather” in Birmingham and was “just not great riding” in Detroit.

He finished third in Birmingham, fifth in Detroit and sixth in St. Louis; in St. Louis he was passed by Justin Cooper and Cooper Webb. Commentators described St. Louis as his third straight “off” outing following a strong earlier run and a midseason crash in Glendale, noting his riding looked subdued on the rough, rutted St. Louis layout and that he did not visibly fight back after those passes.

Despite those results, Tomac remains a four-time race winner this season and was arguably the fastest rider through the first nine rounds. Reports differ on his points status: one account said he retook the championship points lead, while KTM’s post-race release called St. Louis tougher, said the team “didn’t lose too many points” and said the team remained tied for the lead. The standings are tighter — Ken Roczen has won two in a row and closed a 31-point gap to six points — and Roczen and Hunter Lawrence have joined Tomac in a three-rider title fight with five races remaining. Tomac’s ability to regain the early-season form his team pointed to will be decisive in whether he can hold the red plate to the end of the championship.

TransWorld Motocross published a preview video titled “Watch: First Look St. Louis Supercross 2026,” offering an early look at the Dome at America’s Center ahead of round 12 of the Monster Energy AMA Supercross season and targeting fans who want impressions of the venue and track rather than race results or schedules.

6D Helmets sponsored a first-look video that presented press day interviews and on-track footage. Filmed and edited by Tom Journet, the piece showcased Chase Sexton, Eli Tomac, Haiden Deegan, Cole Davies, Jo Shimoda and Hunter Yoder and also served as brand promotion by highlighting 6D’s Omni-Directional Suspension (ODS) technology and broader brain-protection messaging.

Both videos functioned as pre-race visual previews that emphasized track features, rider visibility and equipment technology rather than race outcomes, full schedules or personnel announcements.

Haiden Deegan can clinch the 250SX West championship at the St. Louis Supercross Showdown on Saturday, April 4. He rides for Monster Energy/Yamaha Star Racing and enters the second 250SX East/West Showdown with a 42-point lead in the 250SX West standings, according to AMA Supercross standings. Only two West rounds remain after St. Louis — Denver and the season‑finale East/West Showdown in Salt Lake City — and 50 championship points will still be available; a Deegan victory with teammate Max Anstie finishing fifth or lower would mathematically secure the title. Levi Kitchen sits 47 points back, and a Deegan win in St. Louis would eliminate Kitchen and the rest of the field from contention.

The St. Louis Supercross Showdown is the 12th round of the Monster Energy AMA Supercross Championship and will be held at The Dome at America’s Center in St. Louis. The event is the second of three 250SX East/West Showdowns and counts as round six for 250SX East and round eight for 250SX West.

Qualifying airs on Race Day Live at 1:00 p.m. ET / 10:00 a.m. PT on Peacock, and full live coverage of the night program — including heat races, LCQs and main events — begins just after 7:00 p.m. ET / 4:00 p.m. PT on Peacock. International viewers can follow the same live timing via the SMX Video Pass (Spanish and French audio tracks), and SiriusXM will carry the complete night-show audio feed. Anstie has five finishes outside the top five this year, including a seventh-place result at the first East/West Showdown in Birmingham. Deegan has said he plans to move up to the 450 class for Pro Motocross; clinching the 250SX West title before that move would allow him to focus his preparation on the transition.

Jason Thomas previewed the track ahead of Round 12 of the Monster Energy AMA Supercross Championship, saying the layout and soil conditions at The Dome at America’s Center in St. Louis could be pivotal for the championship. Round 12 is scheduled for April 4, 2026, and the timing late in the season — combined with a familiar, rider-preferred St. Louis layout — was framed as having potential to influence the title race.

The series has returned to St. Louis after last visiting for the SMX Playoff round in September, and organizers and riders brought recent experience with the venue. Many riders noted they enjoy the St. Louis soil because it tends to be more predictable than the surface they encountered in Detroit, a characteristic Thomas highlighted in his track-focused preview of the impending showdown.

Supercross Live released a track-map video and images that take viewers on a lap around the St. Louis layout, giving fans visual context and offering competitors an early look at the lines, rhythm sections and overall flow. The layout preview was presented both as a promotional tool for Round 12 and as a practical resource for teams planning race-day strategy, helping attendees and remote viewers understand the stadium setup and the jump and turn sequences. Organizers and crews are positioned to use the video and images to prepare riders for the specific challenges of the St. Louis course ahead of the April 4 event.

VurbMoto’s reporting focused on official reactions and event-level takeaways rather than a detailed results ledger. The article “Post-Race Press Conference From Detroit Supercross” covered a post-race media session that included riders, team representatives and race officials. Reporters pressed participants about how track conditions and on-track incidents shaped performances and whether any incidents might draw penalties, while team spokespeople provided strategy context and race organizers described operational and safety responses. The conference also addressed health and safety concerns and considered implications for the championship standings and upcoming rounds.

The Detroit round of the 2026 Supercross season was also reviewed with an evaluative recap of event highlights, competitive outcomes, venue atmosphere, event organization and on-track action. That review placed Detroit SX within the broader season and assessed implications for riders and teams without including detailed transcripts, heat-by-heat results or individual race scores. Together, the press-conference coverage and evaluative review emphasized event-level takeaways and official reactions for readers seeking a concise recap and implications rather than a blow-by-blow race report.

Cole Davies continued his breakout dominance in the 250SX at Detroit, winning a third straight main after an audacious charge through the whoops. Riding the Monster Energy Yamaha Star Racing YZ250F, Davies had been fastest in qualifying but his top lap was removed after his bike failed the post-session sound test; Jo Shimoda failed the same test and Seth Hammaker was promoted to P1 on the sheet. Davies won the first heat, then tangled bars with Coty Schock at the start of the main and was 15th at the holeshot stripe before charging through the field, gaining 14 positions and posting the fastest whoops sector time of 6.477 seconds.

He passed Hammaker and won the main by 12.196 seconds, increasing his championship lead over Hammaker from six points to nine. Davies said, “I’ve kind of proved to myself and everybody what I can do,” crediting hard work and family sacrifices and pointing to his whoops speed as decisive.

NBC analyst Jason Thomas called Davies’ whoop riding his biggest strength “by a long shot,” and said the rider had gone from “iffy to certainty” in a very short time after a breakout that began around A1 2025. Thomas described Detroit as a night of breakout performances, individual recoveries and opportunistic results amid intense, crash-prone racing, called the Detroit whoops unusually difficult and noted most competitors were relieved not to have to run them again. He also highlighted Nate Thrasher’s stronger early pace before a crash—attributing earlier inconsistency to a serious shoulder nerve issue that had left him riding at roughly 50 percent despite previously showing pace nearer a top-10 level—assessed Henry Miller’s fifth-place finish as largely the result of capitalizing on a crash-filled main, and recounted an aggressive Cooper Webb pass on Jorge Prado that took both riders down.

The AMA Supercross Championship Official released short-form highlight packages recapping the Detroit stop, issuing pieces titled “450SX Highlights | Detroit” and “250SX Highlights | Detroit.” These releases present condensed overviews of each class’s action from the Detroit venue.

Each package focuses on the most notable moments from its respective series, surfacing standout performances, decisive on-track moments and significant incidents that shaped the races. The pieces are designed as quick recaps rather than full race reports.

Both highlights aggregate key race action into single, high-level overviews and intentionally omit specific competitor names, podium results, detailed statistics and points implications. The available information does not supply full article text.
