GRAND FORKS, N.D. -- North Dakota coach Dave Hakstol announced today that senior forward and assistant captain Mark MacMillan will undergo surgery on Wednesday, to repair a lower body injury and will be out indefinitely.

MacMillan suffered the injury during North Dakota’s 3-1 victory against St. Cloud State on Saturday in Grand Forks. He leads top-ranked UND with a career-high 16 goals in 29 games this season and ranks third on the team in scoring with 25 points.

He also leads UND in faceoff percentage (57.2) and his 13 goals during conference play lead the National Collegiate Hockey Conference (NCHC).

A fourth-round draft pick of the Montreal Canadiens in 2010, MacMillan leads all active North Dakota skaters with 99 points (46 goals, 53 assists) in 151 career games. He is a finalist for both the 2015 Hockey Humanitarian Award and the 2015 Senior CLASS Award.

North Dakota closes out the regular season on Friday and Saturday at Miami in Oxford, Ohio. UND clinched at least a share of the Penrose Cup as NCHC regular-season champion last Saturday and can claim the Cup outright with one point in the series against the RedHawks.
