Australian Marc Polmans has apologised after accidently hitting an umpire in the face with the ball during a Shanghai Masters qualifying match.
Polmans was on match point against Italy's Stefano Napolitano when he hit a volley into the net before smashing the ball in frustration and catching chair umpire Ben Anderson in the face.
The world number 140 was immediately disqualified.
"It was a high pressure situation and I should have reacted better," he said.
"The umpire, Ben, has accepted my apology for my actions. He knows it was unintentional and I shanked the ball on the frame in frustration in the heat of the moment.
