Australia paceman Mitchell Starc is being monitored by medical staff after being hit by a ball just above his knee during training ahead of their T20 World Cup match against Sri Lanka, the team said on Thursday.
Left-armer Starc was struck by a return ball when bowling at practice earlier this week but he trained on Wednesday.
He had not been ruled out of the Sri Lanka game, which starts at 6:00 pm local time (1400 GMT) in Dubai, a team spokesman said.
Video posted in Australian media on Thursday showed Starc grimacing and hobbling away from a net session.
If Starc proves unfit to play, Australia have Kane Richardson in reserve should selectors opt to stick with pace or Ashton Agar if they decide to pick a second specialist spinner.
Starc, one of cricket's premier white-ball quicks, took two wickets in Australia's opening win over South Africa on Saturday.
