Great Britain have suffered an injury scare ahead of this weekend’s Davis Cup semi-final with Australia in Glasgow.

Kyle Edmund, the second-highest-ranked singles player in Britain’s five-man squad led by world No.3 Andy Murray, took a tumble during practice at the Emirates Arena on Tuesday.

Concerned teammates looked on as Edmund was carried to the dressing room for treatment and the full extent of the injury will be determined by medical staff.

Despite reports that the 20-year-old world No.100 needed scans, British captain Leon Smith was quoted as saying Edmund was fine, while an LTA spokesperson added he “hurt himself a little bit during training. We’ll know more tomorrow. Doesn’t look too bad.”

Ironically, Edmund survived a friendly training session on Monday with Scottish football giants Celtic across the road from the Davis Cup venue only to go down on the tennis court.

Should his injury be worse than the British are making out, it would be quite a blow for the Brits in their quest to make the Davis Cup final for the first time since 1979.

A former junior rival of Nick Kyrgios, the talented Edmund won the US Open boys’ title in 2012 before cracking the world’s top 100 for the first time last month.

Without him, skipper Smith would almost certainly be forced to play the out-of-form James Ward against Australian No.1 Bernard Tomic on the opening day.

Ward, the world No.141, hasn’t won a match since reaching the third round at Wimbledon more than two months ago.

World No.174 Liam Broady and Australian-turned-Brit Brydan Klien, ranked 178th, are potential replacement options for Great Britain, whose squad is rounded out by doubles specialists Jamie Murray and Dom Inglot.
