BUFFALO – The Buffalo Bills have released quarterback Matt Leinart, a person close to the team said Friday.

The source spoke on condition on anonymity because the move has yet to be officially announced.

Leinart, 30, joined the Bills on Sunday after quarterbacks EJ Manuel and Kevin Kolb suffered injuries. On Thursday, Leinart’s only game with the Bills, the Heisman Trophy winner and former first-round draft pick completed 3 of 10 passes for 11 yards and two interceptions against Detroit.

After a standout college career at Southern California, Leinart has struggled to find a place within the National Football League. He has had temporary roles with four teams in the last eight years.
