India’s Shikhar Dhawan is set to discover on Tuesday the extent of a thumb injury that threatens the opening batsman’s ongoing participation at the World Cup. Dhawan led India to their second straight win of the 50-over tournament with a 109-ball 117 against reigning champions Australia at the Oval on Sunday but took a hit to his left thumb during the course of his innings. Team physio Patrick Farhart is due to make a decision on the extent of Dhawan’s injury later Tuesday but reports in the Indian media have suggested the 33-year-old has fractured his thumb. The left-handed batsman suffered the injury as a result of a nasty blow from a rising delivery by Australia paceman Nathan Coulter-Nile but still went on to complete his 17th one-day international century.
