Bills OLB Chris Kelsay is out indefinitely with a strained calf. Former South Dakota State defensive end Danny Batten is expected to get the first crack at replacing Kelsay. "Kelsay, after they re-evaluated him last night, he's not going to make it," confirmed Bills coach Chan Gailey. "He's out for a while." Kelsay has just seven tackles and no sacks through four games.
