Leafs centre Frederik Gauthier will undergo surgery after sustaining a horrific injury to his leg in the Marlies’ Game 2 loss to Syracuse on Saturday night.

Gauthier may be out of action for up to six months, as told by Marlies coach Sheldon Keefe to the media.

““It’s a terrible loss, for Freddy and for us. He’s been playing as good hockey as I’ve seen, especially now that he’s been skating and the extra speed he has been bringing,” Keefe said.

Gauthier was hit into the end boards by Crunch defenceman Jake Dotchin, who was assessed a five minute major and game misconduct on the play.

The line of Gauthier, Brendan Leipsic and Kasperi Kapanen has been a top-producing unit for the Marlies in the Calder Cup playoffs. In six post-season outings, Gauthier had collected a goal and three assists.

Brett Findlay is expected to replace Gauthier’s spot as the centre on that line.

The North Division Final resumes with games 3 and 4 at Ricoh Coliseum on Tuesday and Wednesday. Toronto trails the best-of-seven series 2-0.
