Yuvraj Singh injured his hand during nets on Thursday, raising concerns about his fitness for their World Cup Group B match against England on Sunday.
Yuvraj picked up a minor injury on his hand after being hit by a delivery from bowler Shanthakumaran Sreesanth, a Reuters cameraman said.
The explosive middle-order batsman was seen applying ice to the injury before he aborted the training session to seek medical attention.
Yuvraj is the latest Indian player to suffer injury woes as openers Sachin Tendulkar and Virender Sehwag picked up knee problems at the weekend.
Sehwag, who skipped practice for the last two days, was back at the nets on Thursday and showed off his batting skills at the M Chinnaswamy Stadium.
A billion dreams are resting on the Indian team's shoulders as they seek to become the second Indian team, after 1983's 'Kapil's Devils', to bag the 50-over World Cup.
