It’s good news, bad news for the Bills RB room, which seems to be primed to return its lead rusher after Cook missed last week’s action after being declared inactive shortly before kickoff this past Monday. Cook has been dealing with a toe injury since picking it up towards the end of Buffalo’s road loss to the Texans in Week 5, but it seems like he’ll be good to go this weekend against the Titans after being upgraded to a full participant in yesterday’s practice. As for rookie RB Ray Davis, he was a new addition to the Bills’ injury report yesterday after getting a limited session in. Buffalo is calling it a calf injury for Davis, who practiced in full on Wednesday. The timing of his addition to the report suggests that he picked up the designation yesterday during practice and that it’s a new ailment, so fantasy managers will want to monitor his status today and going into the weekend to have a better idea of his availability. Davis could have made some headway in the backfield last week with his 152 all-purpose yard performance against the Jets, but any limitation as a result of this injury will likely dampen his hopes of establishing a more consistent role alongside James Cook. As long as Cook is playing, he’ll be the RB to start this week and moving forward.
