Breida (ankle) is listed as questionable for Thursday's game at Arizona, Eric Branch of the San Francisco Chronicle reports.
Brieda managed only two limited practices this week due to the tender ankle, but that might be enough for him to earn an active status once Thursday arrives. If so, he likely will be limited behind lead back Tevin Coleman, especially with fellow reserve Jeff Wilson healthy at the moment. The 49ers will release their list of inactives about 90 minutes before Thursday's 8:20 p.m. ET kickoff.
