ESPN's Adam Schefter reports that 49ers RB Isaac Guerendo is "unlikely to play" Sunday at Miami because of his hamstring injury.

49ers RB Isaac Guerendo (foot) is active for tonight's game vs. the Rams. He was listed as questionable after only getting in a limited practice on Tuesday. But Guerendo downplayed the injury throughout the week and was reportedly expected to play tonight even before getting through warmups. There have been no reports so far about the rookie's expected workload in this one. He shapes up as a risk/reward fantasy play. Check the new-and-improved Who To Start Tool to see if Guerendo makes sense for your starting lineup. RBs Patrick Taylor and Ke'Shawn Vaughn are also active for San Francisco tonight; RB Israel Abanikanda is a healthy scratch.

49ers RB Isaac Guerendo got his first start and did not disappoint. The rookie ran 15 times for 78 yards while also catching both of his targets for 50 yards. He scored twice on the ground. Guerendo injured his foot late in the game. If that doesn’t cause him to miss time, he has earned the starting role.

Bucs RB Rachaad White managed just 34 scoreless yards on 13 carries in the Week 7 loss to the Falcons. But he was busy in the passing game, hauling in all six of his targets for 65 yards. He tied with WRs Mike Evans and Chris Godwin for the team lead in catches and ranked behind only those two WRs in receiving yards. White's six targets were a solid 14.3% share. And, although the rushing production wasn't big, White at least out-carried RB Ke'Shawn Vaughn 13 to 4. It's getting tough to expect the rushing efficiency to improve. But if White can at least maintain this type of workload share, he should be able to produce as a low-end RB2 in PPR leagues.
