Raheem Mostert Fantasy Football News | Shark Bites

49ers RB Raheem Mostert is questionable to return to Sunday's game against the Lions with a knee injury. We'll pass along an update when we get one.

49ers RB Trey Sermon is inactive for today's game against the Lions. It's a major surprise -- and leaves Raheem Mostert as San Francisco's clear lead RB in a dream matchup. Mostert is a borderline must-start in fantasy. RBs JaMycal Hasty and Elijah Mitchell are behind Mostert today.

49ers RB Raheem Mostert got the start in Sunday's preseason finale and played all 10 snaps on the 1st possession. RB Trey Sermon then played all 14 snaps on the 2nd possession. Those 2 will open the season sharing backfield work. The exact split between them remains uncertain.

49ers RB Raheem Mostert left Wednesday's practice with "apparent back pain," according to insider Cam Inman. "Mostert winced as he reached the sideline and was checked on by trainers, then watched most of the remaining plays from a knee," Inman adds. We'll see how serious of an issue this ends up being. Mostert, of course, has struggled staying healthy over the past 3 seasons -- although he's never had back trouble.

The 49ers are holding RB Trey Sermon out of Sunday night's preseason game against the Chargers. The rookie reportedly sustained a mild ankle injury during the practice week. According to Niners Nation, he returned to the field for the practice in which he came up "gimpy." That indicates it's not an issue we need to worry about. Raheem Mostert and Elijah Mitchell also won't play in the game, leaving more reps for Wayne Gallman and JaMycal Hasty.

The Athletic's believes 49ers RB Trey Sermon might play a role similar to the one Tevin Coleman played back in 2019. "The 49ers liked to begin games with Tevin Coleman at tailback, which both tenderized the defense and kept the 49ers’ home-run hitter, Raheem Mostert, fresh." That season, Coleman out-carried Mostert 137 to 112 in their 14 games together. Such a split would be a win for Sermon in his rookie season. The takeaway here, though, is that it'll be a committee attack in San Francisco's backfield this year.
