Vikings linebacker Blake Cashman may not be available for Sunday’s showdown with the Packers.

Cashman would have missed practice on Wednesday because he is in the league’s concussion protocol. The Vikings issued an estimated injury report because they played on Monday night.

Cashman will have to progress through that protocol quickly if he’s going to have a shot of getting on the field in Green Bay this weekend.

Tight end T.J. Hockenson (wrist, chest) also would have missed practice on Wednesday. Hockenson played 39 of the team’s 48 offensive snaps in Monday night’s loss to Buffalo.

Defensive lineman Tyrion Ingram-Dawkins (ankle), wide receiver Jauan Jennings (calf), quarterback Kyler Murray (hamstring), and linebacker Kyle Van Noy (calf) were the other Vikings listed as out of practice. Safety Jay Ward (knee) and quarterback Carson Wentz (ankle) were listed as limited participants.
