Great Britain's Kyle Edmund has emerged as a doubt for this week's Davis Cup semi-finals in Glasgow due to an ankle injury.
The 20-year-old, who is fighting to be named the second singles player behind Andy Murray, suffered the problem during a practice session at the Emirates Arena on Tuesday.
The young tennis player was due to undergo a scan yesterday, and at the time, GB captain Leon Smith told BBC Scotland that it was "all fine".
Great Britain will face Australia this week, with the winners due to face Argentina or Belgium in November's final.
