ORCHARD PARK, N.Y. (AP) Buffalo Bills receiver Zay Jones has had knee surgery that will prevent him from participating in the team's series of spring practices.

Coach Sean McDermott wouldn't discuss the nature of the injury or which knee was operated on in providing the update Thursday, when the Bills closed a three-day voluntary minicamp. He also didn't have a timetable for when Jones could resume practicing, but said he's not concerned about the rehab process extending into the season.

McDermott said the injury had been bothering Jones for some time, and the team and player decided to have surgery as soon as possible.
