This from Adam Schefter moments ago:
With the Adrian Peterson suspension extending for the rest of the season, the Vikings needed to make another move. Although they signed Dominique Williams to the practice squad, grabbing a veteran for the home stretch wasn't a bad idea, and so the Vikings went and got one.
Tate, who was a second round pick in 2010 by the Houston Texans, has run for over 2,300 yards in just over three season split between the Texans and the Browns. His career with the Browns came to an ignominious end after rushing for minus nine yards on two carries last Sunday against, ironically, the Texans. On the season, he's rushed for 333 yards, 4 touchdowns, and a 3.1 yards per carry average.
Since the Vikings had 53 players on the active roster (Peterson did not count against the active roster while on the exempt list), it was not immediately announced who would be cut to make room for Tate. As soon as that happens, we'll update the story and let you know.
UPDATE 4:10 PM: The Vikings have let us know that tight end and former Minnesota Golden Gopher QB MarQueis Gray was the player released to make room for Tate.
