Rams rookie running back Tre Mason carried 19 times in the Week 9 win at San Francisco, compared to four for Benny Cunningham and zero for Zac Stacy. But coach Jeff Fisher on Monday declined to name Mason the starter or primary option, reports ESPN.com.
Fisher insisted the team hasn't lost faith in Stacy, who's averaged 3.9 yards per carry with one touchdown and two lost fumbles this season.
