Why JJ McCarthy Didn’t Play: Updated Injury Timeline and Vikings’ Quarterback Plan

Rookie quarterback J.J. McCarthy missed the Minnesota Vikings’ Week 5 game in London because of a high right ankle sprain. The team ruled him out before kickoff at Tottenham Hotspur Stadium on Sunday, Oct. 5, 2025, marking his third straight missed start.

Veteran Carson Wentz started in McCarthy’s place and guided Minnesota to a late win over the Cleveland Browns. On the other side, Cleveland handed rookie Dillon Gabriel his first NFL start after moving on from Joe Flacco.

Updated Injury Details and Team Decisions

McCarthy’s injury was diagnosed as a high ankle sprain in late September. According to local reports and team updates, the quarterback has been progressing but isn’t yet cleared for game action. High ankle sprains typically require longer rehab because of the stability and cutting demands for quarterbacks.

The Vikings are expected to reassess his availability after their Week 6 bye. Coaches have avoided rushing him back, hoping extra rest will allow the ankle to heal fully before a potential Week 7 return.

Wentz handled Sunday’s game despite briefly leaving in the first half for evaluation. He returned with a shoulder harness and later engineered the winning touchdown drive. Minnesota’s offensive line was heavily depleted — three starters were out — which affected both pass protection and run blocking.

The team also relied on creative plays. Running back Cam Akers threw a trick-play touchdown to tight end Josh Oliver, and Jordan Mason scored on a short run despite early struggles and a lost fumble.

Depth Chart and Fantasy Football Impact

McCarthy’s absence has forced Minnesota to adapt. Wentz has kept Justin Jefferson and Jordan Addison relevant for fantasy lineups, though pass protection has been inconsistent. Addison was benched for the first quarter due to a coach’s decision, not an injury, and later caught the game-winning touchdown.

Running back Jordan Mason remains the lead rusher while Aaron Jones Sr. is on injured reserve. Despite early ball-security issues and offensive line injuries, Mason produced a solid day and should hold RB2/Flex value after the bye.

Cleveland’s offense leaned on tight ends for its rookie quarterback. David Njoku was the top target and scored, while rookie Harold Fannin Jr. also found the end zone. Cleveland’s heavy two-tight-end sets remain a core part of the scheme.

Bottom line: J.J. McCarthy didn’t play because of a high ankle sprain and will be re-evaluated after the bye. The Vikings leaned on Carson Wentz, creative play-calling, and a patchwork line to leave London with a crucial win.
