Cooper left last week's game against the Chiefs after aggravating his hamstring injury and he wasn't able to heal up in time to play this week versus the Cowboys.
Fantasy Impact:
Michael Crabtree will assume the No. 1 WR for the Raiders in a fantastic matchup versus a Cowboys defense ranked 25th vs. WRs. Crabtree is a top-12 ranked WR across the board, while Seth Roberts, Cordarrelle Patterson, and Johnny Holton will likely cancel each other for targets.
