49ers' Tramaine Brock questionable to play vs. Redskins

San Francisco 49ers cornerback Tramaine Brock is questionable for Sunday's matchup against the Washington Redskins due to a hamstring injury.

Brock missed three consecutive practices all week and did not practice all of last week either. The 26-year-old did not suit up against the New York Giants last Sunday.

If Brock can't play, Dontae Johnson is likely to receive more snaps.
