INDEPENDENCE, Ohio -- The Cleveland Cavaliers made a big change with another season falling apart, firing general manager Chris Grant on Thursday. Grant was fired a day after the Cavs dropped their sixth straight game, an embarrassing home loss to a Los Angeles Lakers team that started with eight players and finished with five. Vice president of basketball operations David Griffin will serve as acting general manager. Owner Dan Gilbert made it clear hes unhappy with what has transpired in a season that began with hopes the Cavs would make the playoffs after a three-year absence. "This has been a very difficult period for the franchise," Gilbert said in a statement. "We have severely underperformed against expectations. Just as this is completely unacceptable to our loyal and passionate fan base, season ticket holders and corporate partners, it is also just as unacceptable to our ownership group." Gilbert also met with reporters at the teams training facility following the announcement. He expressed confidence that the Cavs can show improvement under coach Mike Brown over the final 33 games. Grant was instrumental in the rehiring of Brown, who was fired during his first stint with the team in 2010. Gilbert was asked if Browns job was safe for the rest of this season. "Were going to see Mike Brown succeed this year because I think that hell be able to do good things and I think this team will be able to do good things," Gilbert said. "I think theyre going to look at each other and theyre going to look in the mirror and theyre going to rally." Gilbert also was asked why he decided to change his general manager but not his coach. "Coach Brown has only been here over half a season," he said. "Chris Grant has been here 8 1/2 years. Hes been the general manager almost four years. Theres a lot of talent on this team. I think everybody knows that." Gilbert promised last spring the Cavs would not return to the NBA lottery, but Cleveland is 16-33 and has dropped six in a row -- matching its longest losing streak of the season. The Cavs are 5 1/2 games out of the final playoff spot in the weak Eastern Conference and their only win in the last nine games came over Milwaukee, which has the leagues worst record. "Accountability starts with me," Gilbert said. "I take responsibility for where were at." Grants tenure will be known for not being able to rebuild the Cavs fast enough despite having a slew of first-round draft picks, including two No. 1 overall selections. Grant addressed the teams poor play last week, saying everyone in the organization was accountable, including himself. Grant took Anthony Bennett with the first pick last June and then signed free-agent centre Andrew Bynum during the summer when no other team would offer the 7-footer a contract. Grant was able to unload Bynum in a trade with Chicago for Luol Deng, but the forwards arrival has done little to invigorate the Cavs. Cleveland has been under .500 since the fifth game of the season and the players have been slow to pick up Browns system on both ends of the floor. In a season thats already had too many low moments, the Cavs hit rock bottom Wednesday. Not only did they fall behind by 29 points to Los Angeles, the Lakers played the final few minutes with five healthy players, including one who was allowed to remain in the game after committing his sixth foul because coach Mike DAntoni was out of bodies. The Cavs were booed throughout the game and Brown, who has been unable to come up with any answers to stop his teams skid, benched All-Star point guard Kyrie Irving and three other starters in the fourth quarter as Cleveland got back in the game before losing 119-108. The acquisition of Deng last month brought hope the season could be salvaged, but that proved to be temporary. The Cavs went 3-2 on a West Coast trip, but followed that with a 1-4 record on its longest homestand of the season. Cleveland then lost three consecutive road games, including a 31-point rout by the Knicks on national television. Grant joined the organization in 2005 as vice-president of basketball operations/assistant general manager. He was hired as general manager on June 4, 2010. Griffin was hired later that year after spending 17 seasons with the Phoenix Suns, the last three as the clubs senior vice-president of basketball operations.

The Court of Arbitration for Sport ruling "puts an end to my dreams of being a top player," the 27-year-old Troicki said in a statement. "I worked my entire life for it, and it has been taken away from me in one afternoon by a doctor I didnt know," said Troicki, whose ranking peaked at No. 12 in June 2011. It fell from No. 53 to 77 since he was suspended by an International Tennis Federation tribunal in July. Troickis appeal to CAS was partially upheld, and it ordered him to serve a 12-month ban for skipping a blood test after losing at the Monte Carlo Masters in April. He blamed a tournament anti-doping officer who he claimed advised him to write to the ITF explaining that he was ill and could not give a blood sample. He had already given a urine sample which later tested negative. "The player committed a doping offence, but his fault was not significant," the court said in a statement. Troicki will be cleared to play again on July 15, having missed four Grand Slam events while suspended. "I have no idea about what to do now or where to go. I hope somehow I will be able to fight back," he said. Serbia plays the Czech Republic in the Davis Cup final in Belgrade next week. Troicki appeared in the first two rounds this year. CAS fast-tracked Troickis case to give him the chance of reselection if his appeal had been successful. Troickis Davis Cup teammate and good friend Novak Djokovic lashed out at the World Anti-Doping Agency, saying the decision in Troickis case proved that the fight against doping is badly organized and he does not trust the system anymore. "When you are randomly selected to go and provide the test, blood test or urine test, the representatives of WADA ... who are there in the tournament, are supposed to give you the clear indications and explain you the rules and regulations, and what the severe consequences or penalties that you might undertake or you might have if you fail to provide the test," he said. "The representative, she didnt do that in his case." In 2010, Troicki won the decisive singles rubber in the final against France to give Serbia its first title. Djokovic also criticized the ATP for not standing behind Troicki.dddddddddddd "So Viktor is there by himself. Tomorrow can be anybody else," Djokovic said. "For me this is just another big reason, another example that there are some certain things that have to be changed definitely." Troickis home federation described the verdict as "humiliating and disappointing." "Serbias Tennis Association is deeply disappointed with such a decision," it said in a statement. "Viktor Troicki has been inflicted a major injustice." ITF President Francesco Ricci Bitti said rules had to be applied strictly "to keep our sport clean." "What is harder to accept is criticism of doping control officers who perform a difficult role," Ricci Bitti said in a statement. World No. 1 Rafael Nadal also expressed support for Troicki, who he called "a good guy." "I hope to see him back on tour next year," Nadal said at the ATP World Tour Finals in London. "The doctor who accepted to make the control the next day, if thats that way, thats a big mistake from the doctor, too." The CAS panel acknowledged that the tournament anti-doping officer "should have informed the player in clearer terms of the risks caused by his refusal to undergo a blood test." The court added "there was no suggestion that Mr. Troicki intended to evade the detection of a banned substance in his system." The three-member CAS panel said that Troicki and the doping official, a Ukrainian doctor, gave their evidence in good faith in Lausanne one month ago. However, the panels ruling published by the ITF noted that "the recollection of the athlete in particular was colored by his subsequent reconstruction of events." A one-year ban was considered a "just and appropriate sanction" by the panel, and the minimum required in such a case according to ITF anti-doping rules. The ITF tribunal in July declined to impose the standard two-year ban for a first anti-doping violation because it accepted Troicki was stressed by illness on the day and his long-standing needle phobia. The ITF said Troicki remains disqualified from the Monte Carlo Masters, but retains his prize money and ranking points from subsequent events, including his run to a fourth-round loss against Jo-Wilfried Tsonga at the French Open.
