Mattison (shoulder) doesn't carry an injury designation into Sunday's game against the Panthers, Courtney Cronin of ESPN.com reports.
Dalvin Cook (ankle) also has been cleared, so Mattison likely will be relegated to a backup role. Mattison has eclipsed 100 rushing yards in both spot starts when Cook has sat out this season. Given Mattison's effectiveness and Cook's fragile health, Minnesota may opt to give Mattison a more significant share of the workload than he previously had been receiving with both running backs healthy.
