The Panthers placed Roy (hamstring) on injured reserve Tuesday, Darin Gantt of the team's official site reports.

EDGE Analysis

Roy suffered the injury during Sunday's loss to the Giants. He'll be forced to miss at least four games after being placed on IR, but he could be out longer, with coach Matt Rhule saying it "looked pretty severe." In Roy's absence, Phil Hoskins and Marquan McCall will be the backup defensive tackles behind starters Matt Ioannidis and Derrick Brown.
