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/SWhynoCyber Monday Basketball Jerseys .

Eric ONeal says most of the arrests at Monday nights game were for public drunkenness, though one person was taken into custody on suspicion of trying to steal a seat from the stadium.EUGENE, Ore. -- The defending Olympic pole vault champion warmed up, then cooled down, then ran through the whole process again, as the driving rain pelted the field Friday at U.S. Olympic Trials.The more time you have to think, the more youre like, `Wow. This is how bad things happen, Jenn Suhr said.Suhr escaped the badness. Several other big-name athletes werent as lucky on a rain-drenched afternoon at Hayward Field.On a day that saw LaShawn Merritt lower his world-best mark at 200 meters to 19.74 seconds -- in a semifinal heat, no less -- and two high-school kids, Michael Norman and Noah Lyles, earn spots in the final, there was just as much buzz about those whose chances got washed away in the rain.First among them was hurdler Dawn Harper-Nelson, whose run at a third Olympic medal came to a stunning halt in 100-meter semifinals, when she finished third -- not good enough to make the eight-woman final.Tears are going to come, she said. Right now, Im just in shock.Later, after the rain had stopped but the track was still slick, American record-holder Keni Harrison stumbled to a sixth-place finish and a spot on the couch next month. Brianna Rollins, the 2013 worlds gold medalist, won in 12.34 seconds, a comfortable .16 ahead of Kristi Castlin, who was considered a bigger threat four years ago at trials.Harrison was supposed to be the woman to beat this year.It happened so fast, she said, clearly holding back tears. Ill have to watch film. Its unfortunate, because my season was going so well. But this stuff happens.It also happened to Shamier Little. The worlds silver medalist in 400-meter hurdles didnt make it out of her semifinal heat.Allyson Felix took to the track well before the rain hit, and coasted through her 200-meter qualifying heat in 22.93 seconds. It was her first race in nearly a year at her favorite distance. She said nothings really changed with her aching right ankle, despite four days of rest.Just trying to see how it does on the curve, and all that, she said, as she moved ahead in her quest for the 200-400 double at the Rio Games.Shortly after Felixs race, the sky opened, and everybodys outlook changed. The discus and pole vault competitions were delayed. The 100-meter hurdle semifinals turned into even more of an adventure than usual.I couldnt see through my race, said Nia Ali, who got safely through the semifinal, then finished third in the final, too, to make the Olympics.Suhr, whose gold medal in London came in a windy rainstorm, only needed one jump to qualify for the final.Im thankful to make it, because you never take it for granted, she said.Also waiting out the rain was Tavis Bailey, who finished second in discus finals -- one of the most competitive contests on the card.ddddddddddddWhen raindrops are hitting the discus in your hand, that will get to you, said Bailey, who finished behind Mason Finley.Not so fortunate was defending national champion Jared Schuurmans, who finished fifth.Others with decent chances who didnt make the team included high jumpers Jesse Williams, the 2011 world champion, and Randall Cunningham, who was hoping to join his sister, Vashti, on the trip to Brazil.When you landed on the mat, you landed in puddles, said Cunningham, who does the bulk of his training in bone-dry Las Vegas. Your whole body was soaked.Such is life in track and field -- and everything is amplified in the no-excuses world of U.S. Olympic qualifying, where the top three finishers make it and no exceptions are made for injuries, past performances -- or weather.Nobody felt worse than Harper-Nelson, who burst onto the scene eight years ago at the Birds Nest in Beijing, crossing the line first after her more-ballyhooed teammate, Lolo Jones, tripped on the second-to-last barrier. That day, Harper-Nelson crossed the line and could be seen mouthing the words What? What?She was every bit as dumbfounded by this finish.Complete disbelief, she called it. Ive never been in a position where someone is pulling away and I wasnt able to react.Other happenings on Day 7 of track trials:HURDLES WIN: Rollins stepped ever so slightly into an adjacent lane late in the 100-meter hurdles race but didnt impede fourth-place finisher Queen Harrison, so there was no protest, and no change in the results.SPRINT FAREWELL: Lost in the buzz over the high-schoolers making the 200-meter final was the fact that three longtime mainstays of the U.S. sprint team -- Mike Rodgers, Wallace Spearmon and Walter Dix -- all failed to advance. On the womens side, Jenna Prandini had the best 200 time, at 22.72 seconds.JAGR MASTERY: Evan Jager won the mens steeplechase in 8:22.48. Hell be joined in Rio by Hillary Bor and Donn Cabral.ARIES ADVANCES: Defending Olympic champion Aries Merritt, less than a year removed from a kidney transplant, made it through his qualifying heat in 110-meter hurdles. Also making it were 2008 bronze medalist David Oliver and 2012 silver medalist Jason Richardson.QUOTABLE: Dont mean to brag, but were pretty extraordinary, Lyles, after he and fellow 18-year-old Norman won their heats in the 200-meter semifinals.
