Green Bay Packers left tackle Bryan Bulaga suffered a torn anterior cruciate ligament and is expected the miss the entire season, according to multiple sources.
Bulaga was injured at some point during the Packers' intra-squad scrimmage on Saturday. The Iowa product finished the practice, but later received treatment in the locker room.
The 24-year-old Bulaga missed the final nine games last season due to a fracture in his left hip.
Marshall Newhouse, who started all 16 games at left tackle last year and 13 in 2011 for Green Bay, is expected to move back from right tackle to left.
