Brian Robinson Jr. out for Week 15

The Commanders have ruled RB Brian Robinson Jr. (hamstring) out for Sunday's game against the Rams. That should leave Antonio Gibson leading the backfield. Rookie Chris Rodriguez figures to work in to some degree as well. We have no full games without Robinson yet this season to know how much Rodriguez might get, though. Washington now sits 4-9, coming off the bye, and with a coach who looks likely to get fired at the end of the season. We don't know whether or how any of that will affect workload decisions this week. But there's potential for any of those components to factor in. We're projecting Gibson as the clear leader and a low-end RB2 in our Week 15 RB rankings. Just be careful about overrating him in your lineup decisions.
