The Athletic's Daniel Popper left Chargers RB Kimani Vidal off his latest 53-man roster projection. Popper has RBs Gus Edwards, J.K. Dobbins, Jaret Patterson, and Isaiah Spiller making the team over Vidal, the sixth-round rookie.

The Athletic's Daniel Popper says RB Jaret Patterson "got a notable amount of work with the first team" in Thursday's full-team drills. Rookie RB Kimani Vidal, meanwhile, rotated with Isaiah Spiller and Elijah Dotson with the second team. Patterson spent most of last season on the Chargers' practice squad but finished the year back on the Washington practice squad. He then signed a futures contract with the Chargers this offseason.

Commanders RB Brian Robinson (knee) has been ruled out for Week 18 vs. the Cowboys. RBs Jonathan Williams and Jaret Patterson figure to carry the workload on Sunday. The Cowboys' defense rank as the 4th-toughest matchup for opposing RBs in adjusted fantasy points allowed this season. It would've been tough to trust Robinson or Antonio Gibson, who underwent foot surgery on Thursday, in this game for fantasy purposes. We feel even more skittish about the backups. Neither Williams nor Patterson is anything more than speculative RB3/flex consideration.

Commanders RB Brian Robinson (knee) didn't practice on Thursday. It's not looking good for the rookie at this point, but Friday will give him a chance to participate in a limited fashion perhaps. RB Antonio Gibson was placed on IR already, and the team elevated RB Jaret Patterson from the practice squad in a corresponding move. This messy situation doesn't bode well for any fantasy manager trying to decipher this situation for Week 18 vs. the Cowboys. Check in tomorrow once we have a more concrete idea of what to expect from the Commanders' backfield.
