Breida (ankle), who is listed as questionable on the 49ers' official injury report, is expected to play in Sunday's game in Baltimore, Adam Schefter of ESPN reports.
Breida has missed the last two games due to the injury but was able to return to practice this week on a limited basis. Assuming he's good to go, Breida will poach touches from lead back Tevin Coleman, while reserve backs Raheem Mostert and Jeff Wilson could also see smaller roles.
