Matthew Stafford missed a second consecutive game Sunday at Green Bay, two weeks after suffering a partially dislocated right kneecap in an Oct. 4 loss at Chicago.
But when he'll be back remains a mystery, especially after an abbreviated return to practice last week might have set back his recovery.
Stafford, who started the first four games, took about half the practice reps Wednesday, then sat out Thursday and Friday, reportedly after experiencing more swelling in the knee. As a result, the Lions sent a new MRI of Stafford's injured knee to be examined Monday by orthopedic surgeon Dr. James Andrews in Birmingham, Ala., ESPN's Chris Mortensen reported Sunday.
"It's just gossip," Lions GM Martin Mayhew said. "I'm not going to comment on it, or give it any credence or credibility by making a statement about it."
