ALLEN PARK, Mich. � Detroit quarterback Matthew Stafford is listed as questionable for Sunday�s game at Green Bay.

Stafford has missed four of five practices this week, including Friday�s, with a right knee injury suffered Oct. 8 at Chicago. But coach Jim Schwartz says he won�t decide until Sunday morning whether the No. 1 overall draft pick will play against the Packers.
Wide receiver Calvin Johnson, Detroit�s leading receiver, also did not practice Friday and is questionable for Sunday�s game. His right knee was injured in Sunday�s loss to Pittsburgh.
