Mattison had eight carries for 27 yards in Sunday's 31-30 loss to Tennessee.
Mattison played on 16 of 65 snaps as he still had a decent role even on a day when Dalvin Cook had 181 yards rushing. Mattison had 10 touches Week 1 before just four touches last week, so his role off the bench will be inconsistent, but he has a chance to be involved enough for value in deeper formats, even when Cook is healthy.
