The Buffalo Bills, who open their 2014 regular season Sept. 7 against the Chicago Bears at Soldier Field. said Wednesday that talented young linebacker Kiko Alonso likely will miss the entire season due to a knee injury.

Alonso, who underwent hip surgery this offseason, tore the knee ligament while working out in Oregon, according to the NFL team.

“(Alonso) suffered a torn ACL in his left knee and will most likely miss the 2014 season,” Bills general manager Doug Whaley said in a statement.

“He will be scheduled for surgery in the near future and begin a rehabilitation program at the appropriate time.”

A second-round draft pick in 2013 out of Oregon, Alonso was an NFL defensive rookie of the year contender last season after leading Buffalo with 159 tackles, two fumble recoveries and tied for the team lead with four interceptions.

Buffalo, who have not made the playoffs since 1999, finished last in the AFC East last season with a 6-10 record.
