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 Eagles on Thursday claimed RB Trey Sermon off waivers. ESPN's Adam Schefter reports that the team had previously discussed a trade with the 49ers. Sermon took less than 2 full years to bust his way off the roster of the team that drafted him in Round 3. So it's tough to bet on a big impact from him. But he's immediately the heaviest RB in the Philly backfield. We'll see whether than can make Sermon a quick factor in short-yardage situations.

ESPN's Field Yates reports that the 49ers have waived RB Trey Sermon. That leaves 4 RBs on the roster: Elijah Mitchell, Tyrion Davis Price, Jeff Wilson Jr. and Jordan Mason. We'll see exactly how things sort out behind (or alongside?) Mitchell. Kyle Shanahan backfields have been productive enough that all 4 players are worth a look in fantasy football leagues of varying sizes.

There's been some positive buzz on 49ers RB Trey Sermon this month, but insider Matt Maiocco believes he's on the roster bubble. "If Sermon were not a third-round pick a year ago, there probably would not be much of a conversation about his status," Maiocco writes. He has RBs Elijah Mitchell, Ty Davis-Price and Jeff Wilson as locks to make the team, with Sermon, JaMycal Hasty and Jordan Mason fighting for the final spot. There's no clear-cut handcuff to Mitchell, but Davis-Price and Wilson are better last-round fliers than Sermon.

49ers RB Trey Sermon is dealing with an ankle injury, per HC Kyle Shanahan. The issue popped up in practice on Thursday. It must be minor, though, as Sermon rushed 5 times (for 8 yards) in a preseason game on Saturday.

The 49ers started RB Trey Sermon in the backfield in Saturday's 2nd preseason game against the Vikings, but 2 other RBs also saw touches on the team's 1st drive. San Francisco sat Elijah Mitchell and Jeff Wilson Jr., along with QB Trey Lance and some other starters. Sermon led the RBs who did play, but JaMycal Hasty and Tyrion Davis-Price joined him for 1 carry apiece amid the team's 4-play 1st drive. Sermon was the only RB to garner touches over the next 2 drives and finished the 1st half with 5 carries and 2 targets. vs. 2 total opportunities for each of his teammates. None generated much yardage in that span. Even if Sermon enters the season ahead of Davis-Price and Hasty on the depth chart, he might still sit 3rd behind Mitchell and Wilson in touch distribution. The primary takeaway here should probably be that this remains a crowded backfield.
