In a huge sigh of relief for Indian boxer Vijender Singh, National Anti-Doping Agency (NADA) announced on Tuesday that the boxer has tested negative in the drug test.
London - McLaren driver Jensen Button has refused to play a second fiddle role to teammate Lewis Hamilton, as earlier suggested by team boss Martin Whitmarsh, and believes he could still catch up with the fellow British racer.
Button, who is just 41 points behind Hamilton, said he would keep fighting until his last chance to win the driver's championship diminishes.
"It's not a big margin, it's less than two wins. Until that chance is gone, you're going to fight for it. I'm not here to just race around and help my team-mate win a championship because none of us are," The Sun quoted Button, as saying.
"We're here to fight and do the best job we can for ourselves first of all, and also for the team. I think it would be a pretty boring championship if there are only 12 of us drivers actually fighting for a victory and the rest of us were there to help our team-mates," he added.
"It's not the sort of formula that we should want. So I'm going to be fighting all the way until I either win the championship or it's not possible," he said.
