Offensive lineman Don Barclay proved to be a valuable reserve for the Green Bay Packers a season ago, starting 14 games at right tackle in place of an injured Bryan Bulaga.
Now it looks as though the Packers will have to get by without him.
Barclay fell awkwardly on his right knee and was carted off the field. He was set to enter this season as the primary backup at both guard positions and right tackle.
“You typically don’t get a sixth guy that can play that many positions and has had that much experience with 20 games or started. That will be a big one if he’s down,” guard Josh Sitton said.
Barclay has appeared in 30 games over the last two season for Green Bay with 18 career starts.
