Vikings RB Alexander Mattison (ankle) is inactive for tonight's game against the Packers. With RB Dalvin Cook (shoulder) also out, Mike Boone will serve as Minnesota's lead back. He's a RB2 with upside.

Vikings RB Alexander Mattison (concussion) isn’t listed on the final injury report after putting in a full practice on Friday. He figures to operate as Minnesota’s lead back in a dream matchup vs. Detroit’s 31st-ranked RB defense this weekend.

Vikings RB Alexander Mattison (concussion) got in a limited practice on Wednesday. His status, of course, has taken on increased importance with RB Dalvin Cook out for Week 17. If Mattison can clear protocol, he should operate as Minnesota's lead back in Sunday's dream matchup vs. Detroit's 31st-ranked RB defense.

The Vikings have downgraded RB Alexander Mattison to out for Sunday's game against the Jaguars because of an illness. That elevates Ameer Abdullah to the #2 RB spot for the game -- according to the team's "unofficial" depth chart. That probably doesn't mean a lot of work for Abdullah (or Mike Boone). Perhaps losing Mattison keeps more touches on Dalvin Cook's plate. Ultimately, we wouldn't alter fantasy-lineup plans on this news.

Update: Mattison had an appendicitis and underwent successful surgery, according to NFL Network's Tom Pelissero. Mattison might end up missing more than just this week's game.

Vikings RB Alexander Mattison (ankle) remained sidelined for Thursday's practice. He didn't practice at all last week and seems unlikely to play against the Packers on Monday night. With RB Dalvin Cook (shoulder) also expected to miss that one, Mike Boone will operate as Minnesota's lead back.

Vikings RB Alexander Mattison (ankle) is out for Sunday's game against the Chargers. That leaves Mike Boone and Ameer Abdullah behind Dalvin Cook on the depth chart. Mattison's absence could certainly mean a few extra touches for Cook.
