With Narsingh Yadavs roommate Sandeep Yadav at the SAI Sonepat camp also testing positive for the same banned substance, WFI said that it strengthens the conspiracy theory and points to a clear case of sabotage.The fact that Narisnghs teammate at the camp has also tested positive for the same substance, it clearly looks to be a foul play. Both the wrestlers were consuming the same supplements as they were roommates. It arises suspicion, WFI assistant secretary Vinod Tomar said.There was a high quantity of steroid in the sample, which is hard to believe. It seems like a deliberate thing. Why would anyone take such high dose? he said.Tomars said Narsingh and Sandeep are the only two wrestlers in the camp to have tested positive.Only these two guys have failed the test and this clearly indicates that something is wrong, he saidNADA Director General Navin Agarwal on Sunday confirmed that Narsinghs B sample tested positive for a banned substance. Sources said that he had tested positive for methandienone -- a banned anabolic steroid.With his Olympic dreams in jeopardy after a failed dope test, Narsingh had claimed innocence, saying the entire episode was a conspiracy against him.This is a conspiracy against me. I have never taken any banned substance, said Narsingh.Narsingh, who was picked ahead of the double Olympic medallist Sushil Kumar to represent India at the Rio Games in 74kg Freestyle category, has been handed provisional suspension and his Olympics accreditation has also been withheld.The WFI also cried foul, claiming that Narsingh has a clean history and it was a clear case of sabotage.On the basis of Narsingh bagging the 74kg Olympic quota berth with a World Championships bronze last year, WFI had named him to represent India at the Rio Games and Sushils demands for a trial were rejected by the Federation as well as the Delhi High Court after a lengthy legal battle.

ALAMEDA, Calif. -- Bruce Irvin has joked about being Robin to Khalil Macks Batman as part of a dynamic pass-rushing duo for the Oakland Raiders.With the way Irvin has played the past few weeks, it is time for Robin to get his due.Irvin is coming off perhaps his most productive game of the season for the Raiders after posting two sacks and forcing Philip Rivers into a late-game interception that sealed Oaklands 19-16 victory Sunday to clinch the teams first playoff berth since 2002.Whatever it takes to help these guys win, Irvin said. I know Im very capable of doing a lot of stuff. God blessed me with a lot of athletic ability. If they need me to spy, Ill spy. If they need me to rush, Ill rush. Any way I can help Ill do it.Irvin has seven sacks so far this season -- one off his career high set as a rookie in Seattle in 2012. He has five sacks alone the past five weeks to go along with 18 quarterback pressures and strong play against the run and even in coverage at times.Irvin, a former first-round pick who signed as a free-agent with Oakland this offseason, said he is playing the best football of his career of late as he has teamed with Mack.I think that from the moment that Bruce arrived, he and Khalil had a natural competition or natural kind of bond where they were two alpha males, coach Jack Del Rio said. They were going to push each other really hard every day and compete every day. Bruce has been tremendous for us and is a really great addition to the football team.Irvins improved play has lifted the entire defense. The unit started slowly this season after bringing in several new starters, including Irvin, cornerback Sean Smith, safety Reggie Nelson and rookies Karl Joseph and Jihad Ward.Oakland became the first team in 49 years to allow at least 500 yards in each of the first two games of a season and was on a record pace for yards per play allowed at 6.9 through six games.But the defense has tightened since then, allowing only 5.4 yards per play the past eight games and ranking seventh overall in total defense.I think were finally starting to gel, Irvin said.dddddddddddd Guys are starting to learn guys tendencies, when guys are going to take chances. People can say what they want to say about our defense with the numbers and all that, but when its time to buckle down and get off the field we seem to do a great job of doing that.The Raiders are tied with the third-most takeaways in the league with 26 and have been at their best in the biggest moments of games. Oakland has faced 11 full drives in the final 5 minutes with the opponent having a chance to tie or take the lead and allowed no points in those situations.The Raiders have forced four punts, three turnovers, stopped three teams on downs and benefited from a missed field goal in those situations, including last weeks win against San Diego.We have to close it out, Irvin said of the mindset. If we dont, we feel like we lost that game if they go down and score and beat us in the last minute. Our defense is doing a great job balling up in key situations and getting off the field and sealing the victory for us.Performances like that have changed the perception of the defense and have contributed to Oakland being in first place in the AFC West. Irvin knows what a top defense can do after having been part of one of the leagues best in Seattle when the Seahawks won the Super Bowl following the 2013 season.But he doesnt want to compare the two units.I hate always comparing us to Seattle, he said. Were Oakland. Were trying to set our legacy. Were trying to have teams watch our defense and try to be like us. Seattle is a good defense but were also a good defense, an up-and-coming defense that has made a lot of strides.Game notes The Raiders held a light practice with a short week before Saturdays game. ...
