Grigor Dimitrov has received a walkover into the semi-finals of the Aegon Championships at Queen's after Alexandr Dolgopolov was forced to retire with an injury.
The eighth seed hurt his right thigh during a first-round doubles match with Ernests Gulbis on Thursday.
The 25-year-old failed to recover in time for his quarter-final match, which has resulted in Dimitrov reaching the final four without a ball being hit.
The fourth seed will meet either Stanislas Wawrinka or Marinko Matosevic in the next round.
