Top seed Rafael Nadal has crashed out of the ongoing Australian Open after he was forced to retire hurt in the fifth set of his quarter-final clash against Marin Cilic.

The world number one succumbed to injury on court meaning that his Croatian opponent Cilic will now face British number two Kyle Edmund for a place in the final following his 3-6 6-3 6-7 (5-7) 6-2 2-0 victory.

This development represents only the second time in 264 Grand Slam matches that the Spanish tennis star has retired.

Nadal last retired against Briton Andy Murray in the quarter-finals of the 2010 Australian Open.

Kyle Edmund is having the time of his life after he stunned third seed Grigor Dimitrov in four sets to secure his last four spot.

He saw off the Bulgarian 6-4 3-6 6-3 6-4 to qualify for the semi-final of a Grand Slam title for the first time ever.[tps_header][/tps_header]
