New Delhi, Feb 6 (IANS): India's star cricketer Yuvraj Singh's father Yograj was confident that his son, who is undergoing chemotherapy in the US for a malignant lung tumour, will come back strongly as a champion player.

Yograj, a former international cricketer, thanked the Board of Control for Cricket in India (BCCI) for supporting his son. He said doctors treating Yuvraj at the Cancer Research Institute in Boston have assured him that his son will come back as a champion.

"Yuvraj had chemotherapy and now he is on medicines. Doctors are trying to end it permanently. Doctors are telling Yuvi will come back as a champion. I am thankful to BCCI. Like a father they have treated Yuvraj. If they wouldn't have helped him then it would have been a different story," Yograj said.

Yograj said Yuvraj was responding well to the chemotherapy treatment.

"Yuvi is recovering well from treatment for cancer in the US. And the doctors there say he will come back stronger," Yograj said.

Yuvraj is reportedly being treated by the same doctor who treated legendary cyclist Lance Armstrong, who survived testicular cancer in 1996 and went on to win the Tour de France a record seven times. Yuvraj is also seeking inspiration from Armstrong.

"He is responding well to treatment. In fact, the doctor keeps asking him if he belongs to a very strong bloodline. The doctors are of the opinion that this treatment may take 4-6 months or even a year. He might get well by March. The doctors are saying that Yuvraj will go back as a new champion," he said.
