After Michael Crabtree was removed from Sunday’s game to allow him a chance to prepare for his upcoming showdown with Vitaly Klitschko (pending swapping of contracts), the Raiders sustained a further blow to their receiving corps when Amari Cooper suffered not only a concussion but also a sprained ankle. These injuries likely rob Cooper of his Week 13 availability, while Crabtree was handed a two-game suspension for his part in the fracas caused when he attempted to apprehend a jewelry thief. This could mean the Raiders have to rely more heavily on known commodities like Cordarrelle Patterson and Seth Roberts, but it could also increase the playing time for Johnny Holton.
