Finley said his knee isn't a major concern, but he seemed to agree it might be smart for him to sit out Sunday's game.
"Would it be smart? Of course it would be smart; everybody thinks that," Finley said, according to the Green Bay Press-Gazette. "But I ain't the head coach or the GM, so I'm going to leave that up to them."
The news of Finley's injury comes as McCarthy is weighing the possibility of resting veteran players Sunday, given the Packers already have clinched the No. 1 seed in the NFC.
Left tackle Chad Clifton (hamstring) also practiced, and McCarthy added that a determination on the lineman's status would be made after he made it through Thursday's padded practice.
