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. Cheap Air Max 90 Free Shipping ." 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.

He deserves the opportunity to be in there and he had a very good game against Columbus, regardless of the score line.Bush made four saves on six shots in Columbus, giving up two goals to midfielder Bernardo Anor. The Venezuelan beat Bush low to his left in the 56th minute with a strike from the top of the 18-yard box. In the 75th, Anors right-footed shot from distance curled away from Bush and flew into the top corner of the net for the game-winner.Since joining the Impact in 2011, Montreals backup keeper has started just three MLS matches (0-3-0), played in four CONCACAF Champions League games (2-2-0), and led the team to back-to-back Canadian Championships (3-2-3) in 2013 and 2014.Thats part of being on a team, said Bush, who has yet to record a victory in North Americas highest league. Within a team, you have changes based on different situations. You have to step in when they call upon you.Bush was called upon to replace Perkins, Montreals starter since being acquired by the Impact in 2012. The Ohio native had made all 17 starts for the Impact in MLS before last Saturdays match. The week before, in the dying minutes of a game against Sporting Kansas City, a defensive mistake by Perkins cost Montreal a point and may have ultimately cost Perkins his starters role.Klopas, however, insists the decision to start Bush is simply to reduce Perkins workload.Troy is very good. But with the amount of games, maybe hes not as sharp, maybe hes a little bit tired, said Klopas. Its just about form. Its the same with players on the field. The guys have to understand that if they work hard, theyre going to get opportunities to play. Guys are going to come in and out of form. You have to use the depth of a squad.We have two very good goalkeepers, including a younger guy whos pushing, whos eager to play, but who needs time. (Bush) has been looking good and sharp in training sessions and in the game hes played.If the Impact (3-10-5) hope to record their first road victory of the year, Bush will likely have to put together the best performance of his young MLS career against third-place Real Salt Lake (7-4-8). The last-place Impact have offered their goalies little offensive support this season, scoring a league-low one goal per game.The numbers are even worse on the road. Montreal has just six goals away from Saputo Stadium for a minus-11 goal differential.The lone bright spot going into Thursday may be Maarco Di Vaios rejuvenation. Cheap Air Max 1 Mens. The Italian striker, who had scored just once in eight appearances to start the year, has three goals in his last four games.Di Vaio will be looking to add to Real Salt Lakes recent woes. After starting the 2014 campaign unbeaten in their first 12 games, Jeff Kassars men have lost four of their last seven, scoring just five goals over that stretch.Despite the poor run of form, Real Salt Lake can always rely on Joao Plata and Costa Rican international Alvaro Saborio, who have scored eight and six times respectively this season.Its going to be a good challenge, said defender Hassoun Camara. Theyre one of the best teams of the league. Why not win over there? If were going, its because we think we can get something out of the game. Were not going there just to look pretty.Theyre a good possession team, theyre good with the ball, added Klopas. They have quality players who are comfortable on the ball and in their decision-making. They give good tempo to the game - they know when to speed things up and when to slow things down. They push numbers forward; their outside backs get involved in the game.Since returning from the World Cup break last month, the Impact have put together a few solid performances, but have a 1-3-1 record to show for them.With 16 games remaining on the season, Montreal is currently nine points out of the final playoff spot in the Eastern Conference. Their current three-game losing streak is the teams longest since opening the season with three straight losses.Theres a lot of frustration, for sure, said captain Patrice Bernier. You play well, but you dont get the result, you arent rewarded.Were losing because of minor details. Were losing by one goal; were not getting crushed. At this point in the season, were paying the price for the smallest misstep. Theres a bit of bad luck, sure. We cant give up even the slightest of chances.Bernier assures the question marks surrounding the teams starting goaltender are not an added distraction.Nobodys thinking about that, he said. Were in a period of changes. There may be more changes coming on Thursday. Theres no single player that can be blamed. We all want to win — the coach, the entire team. Were just looking for that winning recipe right now. Its up to us, collectively, to make sure we support all players who have seen better days.Notes: Winger Justin Mapp is questionable for Thursdays game.
