Simon Mantell's London 2012 hopes are in the balance after fracturing a bone in his left foot at the Olympic hockey test event, BBC Sport understands.
The 28-year-old Reading forward sustained the injury in the final minute of Great Britain's 4-2 victory over India on Thursday evening.
Mantell, who had earlier scored GB's second goal, was accidentally hit by the stick of an Indian player.
An X-ray confirmed the injury and he will see a specialist next week.

No timescale has yet been put on his recovery following the injury, in which Mantell fractured the fifth metatarsal bone of his left foot.
However, Mantell will undergo treatment early next week and his ambition to play at the Olympic Games rests on a swift recovery.
Britain's Olympic men's hockey squad is due to be named in mid-June following a tournament in Malaysia.
Both Mantell and older brother Richard, who is not taking part in the test event, have
a history of injuries,
with Richard suffering
a horror injury
at the 2010 World Cup in Delhi.
Under the regulations of the Olympic test event, GB cannot call up another athlete and will compete with a squad of 17 for the remainder of the competition.
GB face Australia at 1700 BST on Saturday requiring victory over the Kookaburras to progress to Sunday's final against Germany.
The match will be shown live on the BBC Red Button and BBC Sport Website.
