Knight, who is listed as questionable for Sunday's game against San Francisco due to an ankle injury, is expected to play, Adam Schefter of ESPN reports.

Knight made an early exit from last Sunday's loss to Seattle after injuring his ankle. He was able to log three limited practice sessions this week, which appears to be good enough for him to take the field Sunday. Assuming he's cleared to play when Arizona releases its inactive list 90 minutes prior to the 4:05 p.m. ET kickoff, Knight may continue to start for the Cardinals but won't necessarily be guaranteed the bulk of the work out of the backfield. Emari Demercado has outproduced Knight in each of the past two weeks and may have earned himself more opportunities on early downs, especially if Knight isn't operating at 100 percent health.
