There is uncertainty over Shubman Gill's availability for India's World Cup opener as he is suffering from high fever. The 24-year-old opener also didn't attend team's three-hour practice session at Chepauk on Thursday afternoon. "He's under the weather, the medical team is closely monitoring him. We are hoping he gets better soon. We will have to wait on more updates from the medical team," a BCCI official had said earlier.
