Fantasy Impact: Rice was starting to gain some fantasy steam, having totaled 10 catches for 171 yards in the two weeks leading up to Sunday. Even though the injury isn't considered severe, he will still have to undergo a battery of tests in order to suit up. If he can play, he has a sweet matchup against the Rams' shoddy secondary.
