Mattison (ankle) was listed as a non-participant on Tuesday's practice estimate.
Mattison racked up 66 yards on 10 carries in Sunday's 3-0 win over the Raiders before exiting with a right low-ankle sprain. His estimated non-participation on Tuesday's report isn't a great sign for his early prospects of playing Saturday against the Bengals. Ty Chandler would be in line to handle the lead role in the Minnesota backfield if Mattison is unable to play this weekend.
