Thompkins has just 10 catches for 87 yards and no touchdowns this season.
Rogers had just skipped one day of practice in previous weeks as he dealt with the physical problem.
The Browns manage just 306 yards of total offense, but took advantage of a number of short fields to score on five drives. The Raiders mostly avoided allowing big plays, but also couldn't come up with any of their own, coming away from the game with just one sack and no turnovers forced.
The Raiders have failed to reach double digits in Fantasy scoring since Week 1, and they probably won't reverse that trend in Week 9 with the Seahawks on the schedule.
