The reigning CWG championis struggling with an unidentified lower-back problem since May and is yet to begin full-fledged weight training. “I have submitted a report to the federation. Now they have to take a decision. I am of the opinion that in such less time it’s not good to take heavy load. The Olympic qualifiers event is approaching and that is more important than the Asian Games,” Sharma told PTI.When pain subsided last week, Mirabai travelled to Mumbai to resume training and start mobility exercises.Vijay said the pain returned yesterday and he doesn’t want to risk aggravating the injury.The World Championship, scheduled to be held in Ashgabat from November 1, will be the first Olympic qualifying event this year.“She is in constant touch with the federation. She was okay but felt slight pain yesterday in training. She stopped training but has resumed it again today,” he added.READ: ‘Indian compound archery team world class, will taste success in Asiad’Doctors across the country were unable to diagnose the cause of pain in her back.“It is a rare problem, the doctors say there might be small tear in the ligament.
