NHL star Crosby concussed, doubt for Penguins season-opener


New York (AFP)

Pittsburgh Penguins superstar Sidney Crosby has been diagnosed with concussion, the team announced Monday, leaving him in doubt for the start of the new National Hockey League season this week.

The Canadian ace, who has a history of concussion problems, was injured during a practice on Friday, coach Mike Sullivan confirmed.

While Sullivan did not give a timetable for Crosby's return, it is doubtful that he will be available for Thursday's opener against the Washington Capitals.

Sullivan said Crosby sat out a Saturday pre-season game after complaining of feeling unwell and also skipped practice on Monday.

"He came to the rink on Saturday not feeling well and we went from there," Sullivan said. "We always have our players' best interest (in mind). ... This one will be no different."

Crosby, 29, won the Stanley Cup for the second time with the Penguins last season and was named MVP in the playoffs.

The Canadian star has suffered long-running problems with head injuries, with his first reported concussion occurring in January 2011.

That knock led to a 10-month layoff before he returned in November 2011 for eight games. Recurring symptoms however sidelined him again and he did not play until March 2012.

Crosby's latest injury comes just after he was named MVP of the World Cup of Hockey, where he led Canada to victory while contributing three goals and seven assists.
