The injuries just keep piling up for the San Francisco 49ers.

Hot on the heels of news that San Francisco is placing cornerback Richard Sherman on short-term injured reserve due to a calf strain, The Athletic reports that cornerback Ahkello Witherspoon is in the concussion protocol.


Witherspoon is an option to replace Sherman and play opposite Emmanuel Moseley over the next three games. The earliest Sherman can return is on October 11 against the Miami Dolphins at Levi's Stadium.
