Ronnie O'Sullivan was knocked out of the China Open after an astonishing fluke on the very last ball of the match.
The rocket's best-of-nine quarter-final against Scotland's Stephen Maguire had reached 4-4, sending the match to a deciding frame.
Even then, however, the two players could not be split. O'Sullivan was ahead and in charge of the frame, but Maguire then came to the table and cleared up to leave the scores level at 62-62.
The referee brought the black back onto the table for a black-ball decider, and two shots later Maguire finished the game off with a ridiculous fluke.
O'Sullivan missed with the first attempt to pot the black, leaving a difficult attempt at a double for the Scot, who missed badly.
But the ball came back across the other side of the table where it clipped both jaws of the middle pocket and dropped in.
The fluke itself was not a particularly unusual one, but for it to happen on the deciding ball of match makes it one of the rarest in snooker history.
O'Sullivan, to his huge credit, chuckled happily at the piece of luck - while Maguire looked mortified to have fluked his way to victory.
