Saints WR Brandin Cooks had surgery on that injured thumb and is actually out 4-6 weeks, per his agent.
Fantasy Impact:
Cooks' best-possible return based on this new timetable is Week 16, a home game against Atlanta. While it's a good matchup, one would have to wonder just how much Cooks is used anyway, so you may want to consider dropping him in redraft leagues. Kenny Stills stands to benefit with Cooks out of the lineup. Pierre Thomas should also return to draw some targets.
