Erie Otters centre and presumptive NHL No. 1 overall draft pick Connor McDavid is out indefinitely after injuring his right hand during a fight Tuesday night.

McDavid was fighting with the Mississauga Steelheads' Bryson Cianfrone at 13:50 of the second period of their OHL game in Erie, Pa., when it appeared he missed Cianfrone with a punch and hit the glass with his right hand.

McDavid was taken to hospital for x-rays and was to see a hand specialist Wednesday for further examination.

The Otters didn't reveal the extent of the injury, but Sun Media's Steve Simmons reported McDavid has "a slight fracture of a small bone in his right hand."

In an interview on TSN 1050 in Toronto, Otters owner and general manager Sherry Bassin said X-rays taken after the game were not definitive enough. Bassin said the specialist would be looking at a "tiny" bone in McDavid's hand but voiced some optimism.

"We're hoping it won't be too long," Bassin said.

McDavid had a goal and an assist prior to the altercation, for which he received a five-minute major for fighting, along with a game misconduct for removing his helmet during the fight.

With his two points Tuesday night, the 17-year-old native of Newmarket, Ont., has scored 16 goals and 35 assists in 18 games this season for the Otters.

McDavid, who rarely fights, is now uncertain for the world junior championship at the end of the year in Montreal and Toronto, where he was expected to be the top star of the tournament.
