The same injured Vikings starting trio continued to sit out practice Friday, the team's final session before Sunday's game against the Colts.

Safety Harrison Smith (ankle), cornerback Trae Waynes (concussion) and guard Brandon Fusco (concussion) were unable to practice all week. Both Waynes and Fusco suffered brain injuries during last weekend's win in Jacksonville. Smith has been held out since the Dec. 1 loss to Dallas.

All three have been ruled out for Sunday.

Receiver Laquon Treadwell (ankle) also did not practice Friday and has been ruled out vs. the Colts.

With Fusco out, the Vikings offensive line is set to start its seventh different combination in the 14th game of the season. During the portion of Friday's practice open to the media, Joe Berger worked between center Nick Easton and right tackle Jeremiah Sirles, apparently filling in for Fusco.

Berger (concussion) is listed as questionable, but could clear the concussion protocol on Saturday after a full practice on Friday.

Running back Matt Asiata (illness) and cornerback Mackensie Alexander (abdomen) are also questionable for Sunday.
