Mattison had four carries for 16 yards and one reception for 24 yards in Sunday's 27-20 win at the Chargers.
Mattison isn't getting many touches with Dalvin Cook healthy, but his 24-yard reception was a key play in the game. He played just 12 snaps on offense as he has a limited backup role with Cook at full strength. Mattison eclipsed 100 rushing yards in both spot starts when Cook has sat out this season, so he's still one of the more valuable backups in the league.
