Sidney Crosby was playing the best hockey of his life. Now his extraordinary year is on hold and no one is sure when he will be back on the ice.Pittsburgh said Monday that its superstar center has been diagnosed with at least his third concussion just a few days before the defending Stanley Cup champion Penguins open their season.Crosby has been in dominant form, clearly they best player in hockey. He finished as a Hart Trophy finalist as league MVP, won the Conn Smythe Trophy as playoff MVP and led Team Canada to the World Cup title just a few months after winning his second Cup with the Penguins.His short- and long-term future is in doubt after another concussion, an injury that has dogged him off and on over six years.Coach Mike Sullivan told reporters that Crosby was concussed in practice Friday and that there was no timetable for his return. The diagnosis came as the Penguins prepare to raise their championship banner Thursday night before a home game against Alex Ovechkin and the Washington Capitals.Sullivan declined to reveal how the concussion happened. General manager Jim Rutherford said Crosby was held out of the preseason finale against Columbus on Saturday because he wasnt feeling well and didnt practice Monday to go through concussion testing.Our medical staff will take the appropriate measures moving forward, Sullivan said.The 29-year-old Crosby took blows to the head during the 2011 Winter Classic and in his next game that year, on Jan. 5 against the Tampa Bay Lightning. He was out until November. A hit Dec. 5 knocked him out until March, with the combined absences limiting Crosby to just 69 games over two seasons from 2010-2012. A broken jaw ended Crosbys lockout-shortened 2013 season.Crosby has 338 goals and 600 assists in 707 NHL games. Four months ago, he led the Penguins to the fourth Cup in franchise history after piling up 85 points in 80 games.Hes obviously an important player for us, Sullivan said. Were fortunate that we have the depth that we have. We believe we have capable people that can help this team win, and thats how well approach it.Concussions have been a thorny issue for the NHL in recent years, as they have for the NFL and other sports. The league stiffened penalties for hits to the head in hopes of reducing injuries, but more than 100 former players have sued the NHL and alleged it had the resources to better prevent head trauma, failed to properly warn players of such risks and promoted violent play that led to their injuries.The NHL upgraded its concussion policies for the upcoming season, giving spotters authority to remove players from the game if there are visible symptoms. That would not have helped Crosby in this situation.Without Crosby, the Penguins will lean on center Evgeni Malkin and winger Phil Kessel to make up for the loss in production. Sullivan isnt concerned about his captains injury causing a leadership void.Asked if its possible that Crosbys concussion isnt that bad, Sullivan said yes. He said Crosby was not discouraged or frustrated by the news.It is what it is, Sullivan said. Injuries are part of our game. Part of the challenge is for us to try to help Sid get healthy as quickly as possible, and thats what were going to do. We dont look at it any other way. For me frustration at this point is a useless emotion.---Follow Stephen Whyno on Twitter at http://www.twitter.com/SWhynoCheap NFL Jerseys Wholesale .

I strongly and firmly believe that.Said Sweden coach Pia Sundhage, who once coached Solo when she was in charge of the U.S. national team: Its OK to be a coward if you win.Carmelo Anthony, Kyrie Irving & Co. survived their second straight strong challenge at the Rio Games, fending off Serbia 94-91 when Bogdan Bogdanovic missed a 3-pointer from the left wing with 2 seconds left that would have tied it.Kevin Durant grabbed the rebound to keep the Americans unbeaten 48 hours after they barely escaped against Australia.On a day that began with another round of rain, South Americas first Olympics lingered under clouds of grief, doping and disrespect.dddddddddddd-Brazils government declared a day of official mourning for a Rio Olympics police officer who died after being shot in the head making a wrong turn into one of the citys slums.-A Chinese swimmer, Polish weightlifter and Bulgarian steeplechaser have been sanctioned for doping offenses , which are being handled by the Court of Arbitration for Sport for the first time.-And in a serious breach of judo etiquette with political overtones, an Egyptian judoka refused to shake the hand of his Israeli opponent after his loss.Other highlights from Day 7:CLOSE CALLS : Rafael Nadal, the singles champion at the 2008 Beijing Olympics, and Spain teammate Marc Lopez won the mens doubles title.
