Cornerback Mackensie Alexander left Sunday's 28-12 win against the Falcons in the second quarter because of a dislocated right elbow.
Alexander, the fourth-year slot corner, will undergo an MRI on Monday, according to coach Mike Zimmer, which will help determine the severity of his injury, which was confirmed by an NFL source. Safety Jayron Kearse played the rest of the game as the Vikings' fifth defensive back.
"He's doing pretty good. The injury's not too bad," Kearse said of Alexander. "He's going to be around ready to fight for us when he comes back."
Kearse, the fourth-year safety, could continue to play the slot role should Alexander miss games and if cornerback Mike Hughes is still unable to play while rehabbing his knee.
