Green Bay Packers offensive tackle Don Barclay tore the anterior cruciate ligament in his right knee and is out for the season.
Barclay was playing right tackle and had the flexibility to also play both left guard and right guard.
Following his injury, Derek Sherrod becomes the top backup as the swing tackle.
Barclay will undergo surgery and should be ready for next season.
