23 Ahkello Witherspoon CB

Witherspoon (concussion) is active for Sunday's game against the Rams.

Witherspoon couldn't muster anything more than limited practice participation this week, but he successfully navigated through the NFL's five-step concussion protocol to gain clearance ahead of the divisional matchup. It's not expected that Witherspoon will face any limitations in a game for which they will need all hands on deck in the secondary to try and slow the Rams' impressive air attack.

Witherspoon (concussion), who is listed as questionable for Sunday's game against the Rams, is expected to play, Ian Rapoport of NFL Network reports.

Witherspoon is one of several banged-up cornerbacks for the 49ers, with Richard Sherman (calf) viewed as a game-time call while Jimmie Ward (hamstring) is doubtful to play. Witherspoon and K'Waun Williams (shoulder) are trending toward playing and could both handle big snap counts if Ward and Sherman are both sidelined.

Witherspoon didn't practice Wednesday but practiced in a limited fashion Thursday. The Colorado product hasn't cleared concussion protocol just yet, but seems on pace to play Sunday. If he does miss Sunday's game, however, Greg Mabin or Jimmie Ward could get more work.

Witherspoon remains in the concussion protocol, but Matt Maiocco of NBC Sports Bay Area reports that the starting cornerback has progressed sufficiently through it so as to participate in non-contact practices. Barring any setbacks, it appears that Witherspoon is on pace to suit up for Sunday's game against the Rams.

Witherspoon was placed in the concussion protocol Wednesday, Matt Maiocco of NBC Sports Bay Area reports.

Witherspoon will need to pass through all five steps of the league-mandated protocol over the next few days to have a shot at suiting up Sunday against the Rams. If the second-year pro is sidelined for any length of time, Greg Mabin, Jimmie Ward (hamstring) and K'Waun Williams (shoulder) could all be in store for more reps in the secondary.
