Packers may be scrambling at left tackle

GREEN BAY, Wis. -- The Green Bay Packers are concerned that starting left tackle Bryan Bulaga may have sustained a potentially serious knee injury in Saturday night’s scrimmage, a source confirmed. The Milwaukee Journal Sentinel was the first to report that it may be a season-ending injury.

I saw the play on which Bulaga was injured. It was on the opening drive of the scrimmage on first-and-goal at the 10-yard line. Bulaga got tangled up with rookie outside linebacker Andy Mulumba and went to the ground. He was slow to get up but remained in the game and played the final two plays of that series.

If Bulaga’s injury ends up keeping him out for any significant length of time, it would seriously hamper the Packers’ vision for their revamped offensive line. They moved Bulaga and guard Josh Sitton to the left side of the line in order to get their two best linemen protecting quarterback Aaron Rodgers' blindside.

The Packers would be left with a couple of options at left tackle. They could move back Marshall Newhouse, who played left tackle the last two seasons but so far had been competing for the right tackle job. If they moved Newhouse back, then rookie David Bakhtiari could play right tackle. Bakhtiari was pushing -- and may have passed -- Newhouse for that spot anyway.

It’s unlikely that Derek Sherrod would be in the mix for either spot. Sherrod, a first-round pick in 2011, still has not been cleared to return from the broken leg he sustained as a rookie and is on the physically unable to perform list.
