Mattison was a non-participant at Wednesday's practice due to a shoulder injury.

EDGE Analysis

Mattison has filled in admirably for Dalvin Cook (ankle) during recent absences in Weeks 3 and 5, racking up at least 150 yards from scrimmage on both occasions and recording a receiving touchdown in the latter contest. Now, Mattison seems to be less healthy than Cook, as he didn't do more than take part in stretching before heading indoors at the start of practice Wednesday, according to Courtney Cronin of ESPN.com. As for Cook, he officially was limited to begin Week 6 prep, so this situation bears monitoring as the week goes on to get a bearing on who among the two will be available Sunday in Carolina.
