What happened to C.J. Stroud?

Stroud hit his head on the turf during a scramble in last week’s game, forcing him to exit early. He did not practice at any point this week and has yet to clear the league's concussion protocol.

The Texans haven't given a timeline for his return, but the earliest he could play is Week 11 against the Tennessee Titans if he clears concussion protocol.

Who replaces him against Jacksonville Jaguars?

"[Mills] has started games in his league before, so there's nothing new for him," Texans head coach DeMeco Ryans said Wednesday. “It is a benefit for him, being able to get the reps throughout practice, get walk-through [reps], getting every single rep that he can get. He's done a good job with that. Today, he did an outstanding job. We were efficient in and out of the huddle, at the line of scrimmage. He did a great job of communicating.”
