Preview the player prop betting lines, stats and more for J.J. McCarthy before his Minnesota Vikings play the Detroit Lions in a Week 9 NFL matchup.

It's been a while since we've seen J.J. McCarthy start for the Vikings. Here's what we know about his status entering Week 9.

Full practice for J.J. McCarthy signals a Week 9 return, aligning with Kevin O’Connell’s “if he’s healthy, he plays” stance ahead of Lions.

J.J. McCarthy was a full participant in Wednesday's Vikings practice for the first time since he suffered a high ankle sprain in Week 2. He's fully set to return to action in Week 9 vs. the Lions. The quarterback spoke to media on Wednesday after practice and gave a short and positive update on his recovery.

Wentz initially sprang into the role after J.J. McCarthy, Minnesota's Week 1 starter, suffered a high-ankle sprain in Week 2 against Atlanta. McCarthy's been sidelined ever since, but has been on the mend in recent weeks.

The Minnesota Vikings put Carson Wentz on injured reserve Monday, paving the way for J.J. McCarthy to return as the starting quarterback. Jim Rich joined FOX 9's All Day with Amy Hockert to dissect the Vikings' decision to have Wentz play despite an injury to his non-throwing shoulder that now requires surgery.

The Vikings appear to be getting some key players healthy as they prepare for this weekend's daunting trip to Detroit to face the Lions. Quarterback J.J. McCarthy, left tackle Christian Darrisaw, and outside linebacker Andrew Van Ginkel — three of the most important players on the roster — were all listed as full participants in practice on Wednesday's injury report.
