Jenkins had limited practice Friday after passing tests for a calf strain that kept him out of the Packers' last game.
Green Bay lists Jenkins, along with fellow starting defensive end Ryan Pickett, as questionable for Sunday.
Pickett didn't practice this week. He aggravated an ankle injury in the Packers' win over Minnesota.
Wide receiver Donald Driver had limited practice after being out two days with a quadriceps injury. Driver is probable.
