Tavon Austin (ankle) is not expected to play in Sunday's Week 17 tilt against the Seahawks. Both FOX Sports' Mike Garafolo and NFL Network's Ian Rapoport are hearing that Austin is unlikely to suit up for the regular season finale. Austin sprained his ankle in Week 14 against the Cardinals and has missed the majority of practices since. Austin Pettis will fill in as the Rams' slot receiver again this week.
