UPDATE 9:09 p.m.: Bryan Bulaga has been ruled OUT for the rest of the game. Alex Light replaces Bulaga the rest of the game.

UPDATE: The Packers have since announced that Bulaga is questionable to return with a knee injury.

The Green Bay Packers have gotten off to a slow start against the San Francisco 49ers, and now they can add a big injury to their list of problems. Bryan Bulaga limped off the field midway through the first quarter and has now headed to the locker room to get looked over by the training staff.
