Buffalo Bills' Chris Kelsay announces retirement

Buffalo Bills defensive end Chris Kelsay has decided to retire from the sport after 10 years with the franchise.

Kelsay, who has played 147 games for the Bills, is retiring after playing just 12 and nine games respectively in the last two seasons.

"As I kind of went back and forth on it, I believe if you think about retirement that much, you're already retired," NFL.com quotes Kelsay as saying.

"So I'm happy with the decision and look forward to the next chapter of my life."

Kelsay made 32.5 sacks during his NFL career.
