Andy Murray had to retire injured against Australia's Jordan Thompson in what is likely to be his final appearance at Queen's.
It was a sad way for the 37-year-old Briton, who is expected to retire later this year, to leave a tournament which he has won five times.
Murray was playing less than 24 hours after winning his first-round match against Australia's Alexei Popyrin.
From the start, he looked uncomfortable during the points and was heavily limping between them.
After being broken in the first game, Murray held serve in the third and asked for a medical time-out at the changeover.
