World No.2 Novak Djokovic has crashed out of the the Monte-Carlo Rolex Masters as the shocks continued in Monaco.
The Serbian, playing his third match back following an elbow injury, went down to David Goffin, who prevailed 6-2 3-6 7-5 in the quarter-finals.
Defeat for Djokovic means all three of the world's top-ranked players are out of the competition after surprise losses for Britain's Andy Murray and Switzerland's Stan Wawrinka on Friday.
Belgian Goffin, who will meet Rafael Nadal in the last four, had not previously beaten a top three player.
That record looked likely to continue when Djokovic established a 4-2 advantage in the deciding set.
