The Carolina Panthers placed fullback Mike Tolbert on the injured reserve-designated to return list on Tuesday, putting him out of commission until at least Week 13.
Tolbert suffered a hairline fracture in his knee in Sunday's loss to Pittsburgh.
This is a hit to a Panthers running game that has been bitten by the injury bug early. DeAngelo Williams suffered a thigh injury and has missed the past two weeks. Jonathan Stewart sprained his knee and his status could be in doubt for this week's game against Baltimore.
Williams is expected back this week however and would be in line for a big workload with Stewart's status very much in doubt.
