Dean Wilson will return to the Monster Energy AMA Supercross 450SX class for the final five rounds of the 2026 championship, joining Quad Lock Honda. The comeback begins at round 13 in Nashville, Tennessee, giving Quad Lock Honda an experienced rider for the closing stretch.

Wilson filled in for Honda HRC Progressive late in the 2025 Supercross series when Jett and Hunter Lawrence were sidelined. He made five 450SX starts in 2025 aboard the factory Honda CRF450R Works Edition, posting results of 17-9-10-10-7 and finishing seventh in the Salt Lake City finale; he has 74 career top-ten 450SX finishes and finished 17th in the 2025 Monster Energy SuperMotocross World Championship.

In fall 2025 Wilson won the AUSX SX1 title with Quad Lock Honda, and earlier in the year he won the UK Arenacross Tour to claim a second consecutive title. On social media he said he wasn’t sure where he stood in the 450 class but had “put in a good effort” and has been working on his preparation in recent weeks; he invited fans to visit the Quad Lock Honda rig and confirmed he will see fans and competitors in Nashville as he resumes competition for the closing rounds.

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.
