Cooper Kupp heading to IR

The Rams will place WR Cooper Kupp (hamstring) on IR, according to NFL Network's Ian Rapoport. That knocks Kupp out for at least the first four games of the season. Hopefully he's ready to go come Week 5 and the hamstring trouble doesn't resurface. Kupp is certainly worth stashing in all fantasy leagues. Van Jefferson figures to operate as Los Angeles' No. 1 WR with Kupp out. We'll see how the WR corps shakes out behind him. TE Tyler Higbee should also see a bunch of targets sans Kupp.
