Halton (ankle) is questionable to return to Sunday's game against Arizona, Jennifer Lee Chan of NBC Sports Bay Area reports.
Halton had to be helped off the field by trainers after sustaining an ankle injury, and he's been taken to the locker room for further evaluation. Naquan Jones, Kevin Givens and Sebastian Valdez are all in line for more defensive snaps for as long as Halton is out of the game.
