Bills sign DB Nickell Robey to extension

The Bills agreed to a contract extension with defensive back Nickell Robey on Sunday, the team announced.

Robey was entering the last year of his rookie contract. He produced 46 tackles and one sack in 16 games last season.

"Nickell Robey has been a productive and dependable cornerback for our team since we signed him in 2013," Bills general manager Doug Whaley said. "I commend our scouting staff for identifying and signing a player of Nickell's caliber in the undrafted college free agent period. Since entering the NFL, Nickell has worked hard and taken advantage of his opportunities to make plays when called upon."
