The Saints placed WR Michael Thomas on IR with his knee injury. He's out for at least the next four games, which makes Week 16 his earliest possible return date. Thomas would be tough to trust in fantasy lineups at that point. He can be dropped from redraft rosters. His absence should leave WRs Rashid Shaheed and rookie A.T. Perry in full-time roles. See where those guys sit in the Week 12 WR rankings.
