Ron Rivera spoke to the media this morning and gave some updates following yesterday’s win over the Jacksonville Jaguars. Rookie DT Phidarian Mathis suffered a serious knee injury and was getting an MRI as Rivera spoke. He was concerned with the amount of snaps starters Jonathan Allen and Daron Payne got, and talked about shifting other players like Efe Obada into the rotation along with Daniel Wise. Rivera expects to add multiple DTs to the 53-man roster if Mathis’s injury is as bad as feared. They are also looking at some young players for the practice squad. Wes Schweitzer(hamstring) and Jonathan Allen(groin) are also getting MRIs today, but their injuries aren’t expected to be serious.
