The Green Bay Packers canceled practice Monday amid reports that starting left tackle Bryan Bulaga suffered a season-ending knee injury over the weekend.

The injury apparently happened during the team's annual family night scrimmage on Saturday.

Bulaga took all the first-team snaps at left tackle during the scrimmage and was also on the field-goal protection unit at the end of practice. Afterward, Bulaga reportedly told trainers one of his knees was bothering him.

Just three months ago, coach Mike McCarthy decided to shuffle the line, moving Bulaga from right tackle to left tackle, Pro Bowl guard Josh Sitton from right guard to left guard, T.J. Lang from left guard to right guard and Marshall Newhouse from left tackle to right tackle.
