The injury occurred early in the third period, with the Sabres trailing New Jersey by two goals. Devils defenseman David Schlemko rode Kane into the end boards, and Kane's leg appeared to get crammed into an awkward position.
Kane left the game immediately and did not return.
Any major injury would be an incredibly unlucky setback for Kane, who missed most of last season after undergoing season-ending shoulder surgery in February. He was traded from Winnipeg to Buffalo shortly afterwards, so you know he was looking forward to the fresh start with the Sabres this season.
The former fourth overall pick in the 2009 NHL Entry Draft, Kane has only eclipsed the 50-point mark once in a career marred by off-ice drama in Winnipeg and multiple coaching changes. Kane has three points in seven games so far this season in Buffalo.
