Orchard Park, NY (SportsNetwork.com) - Buffalo Bills linebacker Kiko Alonso underwent surgery to repair a torn anterior cruciate ligament.
Bills general manager Doug Whaley confirmed the procedure on Friday, adding that Alonso will return to Buffalo after training camp to begin rehabilitation.
Alonso suffered the injury while working out in Oregon, the club revealed earlier this month.
The 23-year-old former Oregon Duck led the team in tackles last season as a rookie. He started all 16 games after being drafted in the second round out of Oregon and finished with 159 tackles, two sacks and four interceptions.
