Bills DE Chris Kelsay is retiring from football.

The Bills can save $4.9 million by releasing DE Chris Kelsay.

Bills DE Chris Kelsay (neck) has been cleared to begin working out.

Kelsay suffered a torn ligament in his neck and was placed on injured reserve after Week 12. The ten-year veteran recorded two sacks in a reserve role last season, and is due a $3.725 million base salary in 2013. He'll be set to go for OTAs.

Bills placed DE Chris Kelsay (neck) on injured reserve, ending his season.

Kelsay aggravated the torn ligament in his neck during Week 12. The ten-year veteran was turned into a rotational end this season thanks to the Bills' revamped front seven. He finishes with just two sacks and a career-low 14 tackles in nine games. Kelsay's on-field production isn't worth the $3.725 million he's owed in 2013.

Bills coach Chan Gailey hinted that DE Chris Kelsay (neck) could end up on injured reserve.

Kelsay aggravated the torn ligament in his neck against the Colts in Week 12. "Kelsay's still not good right now," Gailey said. "He's still not good. I don't know how that's going to work out, to be honest with you." Kelsay's 10th season in Buffalo is proving to be his worst as he has just two sacks in nine games.

Bills DE Chris Kelsay aggravated his neck injury in Sunday's loss, and "could miss some time."

Kelsay was suiting up Sunday for the first time since Week 9. If "some time" is anything more than 1-2 games, he could be a candidate for injured reserve. Kelsay has been starting in the absence of RE Mark Anderson (knee surgery). Anderson will likely be sidelined at least 1-2 more weeks.

Bills DE Chris Kelsay (neck) particpated in Monsday's practice, and expects to be active for Week 12.

"I definitely plan on playing," Kelsay said. "Hopefully, it's something that time and rest will heal, and we'll move forward. Structurally, everything's sound." Kelsay revealed Monday his injury was actually a torn neck ligament, but says he's not putting his body at further risk by playing. With RE Mark Anderson (knee surgery) still sidelined, Kelsay will start opposite Mario Williams if he can go against the Colts.

Bills DE Chris Kelsay (neck) has been ruled out for Week 11.

With Mark Anderson (knee surgery) out indefinitely, the Bills will remain thin at defensive end opposite Mario Williams. Kyle Moore and Shawne Merriman will likely rotate snaps against the Dolphins.

Bills DE Chris Kelsay (neck) has a 50-50 shot of playing in Thursday's game against the Dolphins.

Kelsay missed the Week 10 loss to the Patriots and now the short week is working against him. The Bills will also be without fellow DE Mark Anderson (knee). Kyle Moore and Shawne Merriman are next up on the depth chart opposite Mario Williams.

Chris Kelsay (questionable, neck) is not expected to play in Week 10 against the Patriots.

Kelsay suffered a mid-week neck injury, and his status for Sunday will likely come down to a game-time decision. If Kelsay is ruled out, Kyle Moore and Shawne Merriman will replace him in the starting lineup. Mark Anderson (out, knee) is hoping to avoid season-ending surgery.

Bills DE Chris Kelsay called out Buffalo's defense on Monday, suggesting some Bills players aren't giving 100 percent on the field.

"We've got to understand what accountability means across the board, playing hard every play," said Kelsay. "You watch the film and not everybody was playing hard every snap and that's unacceptable." Added Kelsay, "I'd take Mario Williams at full health and full speed probably over anybody else in the league. At the same time I'd take Sean Ferguson, who we cut, over a guy that's playing 50 percent, and I think our coaches would too."

Bills DE Chris Kelsay's snaps will be scaled back "significantly" in 2012.

He may not even start after the offseason additions of LE Mario Williams and RE Mark Anderson. Kelsay, now entering his age-33 season, registered five sacks and two forced fumbles in 12 starts a year ago. Expect his stats to dwindle.

Coach Chan Gailey says the Bills will still use multiple defensive fronts despite their official switch to a 4-3 scheme.

"When we hand you a lineup card, it's going to have two defensive tackles, two defensive ends, and three linebackers," Gailey said. "But how much we end up in even spacing (or) odd spacing ... that's determined by players and the offense we're playing." The Bills will mix in some 3-4, but new DC Dave Wannstedt has only ever coached 4-3s. Finding 4-3 players will be a priority in the draft.

Bills OLB/DE Chris Kelsay (calf) has been ruled out for Week 10 against the Cowboys.

Kelsay has been hindered by the injury for over a month now. Danny Batten, Arthur Moats, and Spencer Johnson have been rotating in as the Bills continue to show more 4-3 looks with NT Kyle Williams out.

Bills OLB Chris Kelsay (calf) is expected to return to his starting job against the Redskins this week.

Kelsay will start on one side with Danny Batten on the other. Coach Chan Gailey plans a rotation, however, with Arthur Moats and Spencer Johnson also seeing plenty of snaps. With Kyle Williams and Shawne Merriman out, the Bills are still a terrific matchup for opposing fantasy players.

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.

Bills signed OLB Chris Kelsay to a four-year extension through 2014.

The Bills must have seen something from Kelsay that we haven't. While he's been an active tackler (19 stops), Kelsay's primary role as a 3-4 outside 'backer is to rush the passer, and he's sack-less through three games and hasn't contributed on a single turnover. Making the deal even more of a head scratcher, Kelsay hasn't drawn high marks for his run defense or coverage. His best years clearly behind him, Kelsay turns 31 in October.

The Bills are reportedly closing in on an extension for LB Chris Kelsay.

This is pretty surprising. Kelsay has struggled badly in his transition from 4-3 defensive end to 3-4 outside linebacker, and has yet to record a sack. He's also a major liability in coverage on the strong side. The Bills' head scratching decision making continues. According to the Buffalo News, "it's believed the deal could be finalized within a week."
