Panthers MLB Jon Beason was held out of Wednesday's practice after his knee "flared up" Monday.
Beason was expected to return following the Panthers' Week 6 after sitting out in Week 5, but the smart money is now on first-round pick Luke Kuechly getting another start in the middle. Beason's grip on his starting job is almost certainly loosening.
Panthers placed LB Kenny Onatolu on injured reserve with a torn triceps, ending his season.
CB Ron Parker was promoted from the practice squad to take his roster spot. A special teams ace, Onatolu had five tackles in four games this season. He's signed through 2014.
