RIO DE JANEIRO, Brazil -- The world players union on Friday accused World Cup organizer FIFA of failing to protect Uruguay midfielder Alvaro Pereira after he played on following a hard blow to the head that he said felt "like the lights went out." Pereira lay motionless after colliding with Raheem Sterlings knee in the 61st minute of Uruguays 2-1 victory on Thursday. Even though he appeared like a punch-drunk boxer, Pereira ultimately was allowed to return in the 63rd minute. The union urged FIFA "to conduct a thorough investigation into its own competition concussion protocol which failed to protect Uruguayan footballer Alvaro Pereira." It asked for "urgent talks and immediate assurances that FIFA can guarantee the safety of the players." It also suggested possible rule changes so players suspected of being concussed can be temporarily substituted while theyre diagnosed. "Football is awash with incidents in which players suffer potentially concussive blows to the head and stay on the pitch. In Pereiras case, he demanded to play on, overruling advice from Uruguays team physician for him to be immediately substituted," FIFPro said in a statement. "FIFPro understands that in certain moments, faced by the pressures of such an important international stage, many players would react in this way. There are times, however, when the players also require greater protection against the prospect of making any rash decisions." As he slid for a ball just outside Uruguays penalty area, Pereiras temple inadvertently struck Sterlings left knee. "After the hit, I only recall that I was unconscious for an instant," he said. "It was like the lights went out a little bit." Teammates surrounding the motionless player signalled for a stretcher. Team medical staff came onto the field. Pereira wobbled to the sideline. Uruguay physician Dr. Alberto Pan signalled for a substitution. Pereira seemed to be having trouble maintaining his balance. He argued and angrily wagged a finger to signal he didnt want to be substituted. "I said sorry a thousand times to the doctor because I was dizzy. It was that moment your adrenaline flowing in your body, maybe without thinking ... what I really wanted to do was to help get the result," the 28-year-old Sao Paulo FC player recalled. "What really matters is that everything is OK. Nothing happened. It was just a scare". Pereira said a team doctor and a FIFA physician checked him after the match. There was no immediate confirmation on whether he sustained a concussion, a subject that is slowly moving up the agenda in the sport. FIFPro said it would monitor Pereiras health on Friday. "He must be subjected to further evaluation and follow-up procedures that help determine if and when he can return to training," it said. The union said it also is considering appointing its own independent doctors "for all future FIFA competitions." "The World Cup must set the standard for player health and safety to educate the international football community. Medical evidence shows that a person faces the risk of very serious brain injury, or worse, if he or she suffers a severe head trauma from a concussive blow," FIFPro said. "Furthermore, FIFPro states any sideline concussion assessment must not be conducted solely by a national team physician. In order to ensure real independence, FIFPros involvement, as the international authority representing the interests of the players, would ensure they are insulated at all times." In the English Premier League, Tottenham came under scrutiny in November for an incident involving goalkeeper Hugo Lloris. Currently with the France squad at the World Cup, Lloris was allowed to play on after he was briefly knocked unconscious during a game after colliding with Evertons Romelu Lukaku, despite medical advice he leave the match.

So this was one unusual postponement. The game between the Colorado Rockies and Cincinnati Reds was called off Saturday night because of a water main break just steps from the primary entrance to the ballpark. It will be made up as part of a split doubleheader on Sunday. The first game will start at 4:10 p.m. EDT and the second at 9:10 p.m. The Rockies originally said the game would be delayed 30 minutes, and that city officials were on their way to fix the issue. There were pools of water visible on the street and sidewalk near Blake Street. Restrooms inside Coors Field were not working and there were only limited concessions as the water was turned off to the stadium. Yellow tape was put up to keep fans away from the street and police officers patrolled the area. About 45 minutes after the scheduled first pitch, the Denver Office of Emergency Management requested the game be postponed. "We were told no restrooms. No concessions. You have to have them," said fan Don Evans of Denver. "Important parts of a game. They told us theyd have everything fixed." Stacy Chesney, a spokesperson for Denver Water, said a pipe installed in the 1900s ruptured around 7:30 p.m. EDT. She also said Coors Field was the only customer in the area without water. "Were working as fast as possible to get it repaired," Chesney said. "Were really sorry for the inconvenience to the fans." All this with the sun out and the temperature in the high 80s. "I wasnt sure what was happening," said Reds manager Bryan Price, who met with Rockies skipper Walt Weiss at home plate for several minutes before the game was scrubbed. "There was water on the road, and next thing they are calling the game." Rockies second baseman Josh Rutledge was just as stunned. He said it reminded him of a time when he was with the Tri City Dust Devils in Pasco, Washington, during rookie ball and a fire in the area interrupted a contest. "But I dont know if the game got cancelled," Rutledge said. "You cant make this stuff up." This has simply been that kind of season for the Rockies. Theyre last in the National League and in danger of losing 100 games for the first time in their history.dddddddddddd "Whatever can happen will this year," Ryan Lewis of Billings, Montana, said. "Id be surprised if we didnt have a hurricane." The impromptu postponement did help out a few banged-up sluggers. Reds first baseman Todd Frazier was going to take a second night off with a strained lower back. For the Rockies, first baseman Justin Morneau was a late scratch with a stiff neck. Honouring HELTON The Rockies will retire Todd Heltons No. 17 in a ceremony Sunday. The longtime first baseman wrapped up his 17-year career in the Mile High City last season, departing as the franchises career leader in games played (2,247), hits (2,519), doubles (592), homers (369) and RBIs (1,406). Helton will be the centre of attention, something he never really craved during his career. "Hes going to have all the eyes on him," said outfielder Michael Cuddyer, who was activated off the disabled list Saturday after missing more than two months. "I know hes going to feel awkward, but he deserves to feel awkward." Cuddyer firmly believes Helton belongs in Cooperstown. "Hes a Hall of Famer," Cuddyer said. "Id put his numbers up to anybodys. Hes up there with them." TRAINERS ROOM Reds: INF Brandon Phillips (left thumb) was 0 for 2 with a walk and played seven innings during a rehab game with Triple-A Louisville on Friday. Price wants to see how the rest of the weekend goes for Phillips before making any decisions on when he might rejoin the team. "Were anxious to have him back," Price said. Rockies: LHP Franklin Morales missed his start Friday when his wife went into labour. Morales proudly announced his wife had a girl they named Mariana Elena. She was born at 5:37 p.m. Friday and weighed 6 pounds, 11 ounces. UP NEXT Reds: RHP Mat Latos (4-3) will start the first game and RHP Dylan Axelrod the second. Axelrod is taking the place of Homer Bailey, who was placed on the 15-day disabled list Saturday with a strained right elbow. Rockies: RHP Jordan Lyles (6-1) gets the ball in the afternoon contest and LHP Yohan Flande (0-5) will go that night. Flande will try for his first major league win in his eighth start.
