New Orleans Saints defensive lineman Mitchell Loewen suffered a high-ankle sprain in Sunday's 36-20 loss to the New England Patriots, according to a source familiar with the situation.
The 6-foot-5, 275-pound Loewen went down at the 3:29 mark of the fourth quarter and was helped off the field by the Saints' trainers to the bench area of the sidelines.
He appeared unable to place weight on his left leg before the Saints training staff placed him on a cart to be taken to the locker room.
Loewen, who played on six defensive snaps and 11 special teams snaps, was later observed on crutches after the game.
