MOSCOW -- Russian sports minister Vitaly Mutko, who has come under scrutiny in Russias doping scandal and was banned from attending the Rio de Janeiro Olympics, was promoted to a deputy prime minister on Wednesday.President Vladimir Putin approved a proposal by Prime Minister Dmitry Medvedev to appoint Mutko to a deputy premiership in charge of sport, tourism and youth policies, in a decision shown by state TV.Mutkos longtime deputy minister, Pavel Kolobkov, a former gold medal-winning Olympic fencer who has represented Russia at the World Anti-Doping Agency, moves up to become the new sports minister.Mutkos elevation comes despite him having been personally accused by World Anti-Doping Agency investigator Richard McLaren of ordering the cover-up of a failed drug test by a foreign soccer player.Mutko was also denied accreditation to the Rio Olympics in August by the IOC after being named in the McLaren report. He has denied wrongdoing and suggested the report was biased against Russia.Mutkos anti-doping adviser, Nataliya Zhelanova, and one of his deputies at the sports ministry, Yuri Nagornykh, have been suspended on Putins orders since July, when McLaren accused them of helping to orchestrate cover-ups of hundreds of drug tests.Mutko becomes one of nine deputy prime ministers in Russia, a title which adds to the wide array of other posts he holds. In addition to his governmental duties, Mutko is a member of the ruling council of world soccer body FIFA, chairman of the organizing committee for the 2018 World Cup in Russia and president of the Russian soccer federation.As well as the increase in rank, Mutkos new role reportedly gives him back powers over youth affairs and tourism, which were previously under his control when they were separated from the sports ministry by Putin in a government shake-up in 2012.There have been sporadic signs of discontent among some Russian sports figures over Mutkos leadership. Last month, he survived a leadership challenge as head of the soccer federation, a non-governmental organization. Mutkos main rival accused him of using the sports ministrys authority to coerce voters at the federations conference and suggested some had been threatened with losing their jobs for failing to back Mutko.Mutko personally intervened to cover up a doping case of at least one foreign (soccer player) in the Russian League, according to email evidence obtained by the WADA inquiry led by McLaren.The report alleged an additional 11 positive tests of Russian soccer players were made to disappear in a state-sponsored doping program from late 2011 to 2015.WADAs executive board called on FIFAs independent ethics court to act against Mutko, who has been a member of the scandal-scarred soccer bodys ruling panel since 2009.Among seven key demands, WADA leaders urged FIFA leaders to look into allegations concerning football (soccer) and the role played by a member of its executive committee, Minister Vitaly Mutko.

Howie Long Raiders Jersey . -- Anaheim Ducks defenceman Luca Sbisa will be out at least six weeks with a torn tendon in his right hand.Rafael Nadal has been knocked out of the Miami Open, after being forced to retire from his second round match against little-known Bosnian Damir Dzumhur. After slipping 3-0 behind in the deciding set, Nadal required medical treatment before deciding to call it a day after 109 minutes on court.The Spaniard said he started feeling dizzy towards the end of the first set and later withdrew claiming he was too scared to continue. However, the No 5 seed appeared to be cruising during the early stages of the contest as he raced through the opening set, which he took 6-2 in just 44 minutes.Dzumhur, who was broken twice during the set, did not help his own cause by sending down five double faults while the 29-year-old from Mallorca conceded just five points from his four service games.But everything was to change dramatically after that, with Nadal losing his serve twice during the second set which his 23-year-old opponent claimed 6-4 in temperatures close to 90 degrees.And after Nadal had suffered two more breaks early in the decider, and slipped 15-30 down in game four, the 14-time Grand Slam champion disconsolately shook hands with the delighted Dzumhur. Nadal walks off court after retiring against Damir Dzumhur It had been 443 matches and six years since Nadal last retired on the ATP Tour, when he was beaten in the quarter-finals of the Australian Open by Andy Murray.ddddddddddddNadal admitted: Everything was fine until the end of the first set and I started to feel not very good. It was getting worse and worse and worse.I get a little bit scared to be too dizzy and to lose fluids. I called the doctor a couple of times. I decided I was not safe. I wanted to finish the match but I decided I would not.Hopefully its nothing. Hopefully its just the extreme conditions out there, the beginning of a virus combined with the conditions.Nadal, a four-time Miami finalist but never a champion, lost 22 of the last 29 points on the Stadium Court.Watch the Miami Open live on Sky Sports 3 - your home of tennis.By purchasing a Sky Sports Day Pass for £6.99 or Sky Sports Week Pass for £10.99, you can enjoy access to all seven Sky Sports channels and watch on a TV with a NOW TV Box or on a range of devices.
