Kiko Alonso undergoes ACL surgery

Kiko Alonso's agent has announced that the player has undergone surgery to repair his torn anterior cruciate ligament.

The Buffalo Bills linebacker sustained the injury during an off-season workout earlier this month, ruling him out of the 2014 NFL season.

Steve Caric wrote on Twitter that Alonso underwent the procedure on Thursday, and that it was a success.

Alonso made 159 tackles, two sacks and a forced fumble during the 2013 season, which was his rookie year in the league.
