Britain’s Aljaz Bedene was forced to retire from his second-round match against Alexander Zverev at the Shanghai Masters with a knee injury.

Bedene, ranked 48th in the world, was trailing 4-0 when he ended the match after just 12 minutes on court.

It is the second time in two weeks that Bedene has retired mid-match, and the seventh time in his career.

World number four Zverev will go on to play Argentina’s Juan Martin del Potro in the third round.
