GREEN BAY, Wis. (AP) - Undrafted rookie free agent Don Barclay may not be Green Bay's answer at right tackle, but the Packers' coaching staff is at least entertaining that possibility.

The 23-year-old Barclay took over at the position after veteran T.J. Lang went down with a left ankle injury with 6:42 left in the first half of Sunday's 23-14 victory over the Minnesota Vikings.

Coach Mike McCarthy said Barclay did well and now the Packers must decide if Barclay played well enough to merit starting Sunday night at home against Detroit.

If Lang is able to play Sunday night, he could return to his left guard spot and Barclay could get the nod at right tackle.
