David Nalbandian Video: Watch Tennis Star Get Disqualified for Injuring Linesman

Argentine tennis star David Nalbandian was disqualified at the Aegon Championships final at London's Queen's Club on Sunday after kicking a line judge's leg out of frustration.

Nalbandian was leading when he lost his cool and went to kick an advertising board, accidentally bloodying the nearby line judge, who suffered a cut to his leg, according to the BBC.

UPDATE: Monday, June 18 at 12 p.m. ET

Police will investigate the Nalbandian incident, according to Yahoo! Sports' Stephen Wilson:

"

Police are investigating an assault complaint filed against David Nalbandian after the Argentine tennis player kicked an advertising board and injured a line judge during the Queen's Club final.

London police declined to say who made the complaint against Nalbandian, who was defaulted from Sunday's match against Marin Cilic in the grass-court Wimbledon warmup event.

"

---------- END OF UPDATE ---------

The disqualification gave the 25th-ranked Croatian, Marin Cilic, his first career win at the ATP grass-court tournament. 

Meanwhile the 30-year-old Nalbandian, who was once ranked as high as No. 3 in the world back in early 2006, will look to bounce back by getting past the third round at this summer's Wimbledon.

Nalbandian blew a golden opportunity to win his first Aegon Championships final, leading 7-6 (7-3), 3-4 before the epic meltdown. Although he had just been broken and the second set was slipping away, he was still in relative control of the match.

The Argentine will now be kicking himself after giving away Sunday's final match, as he is unlikely to even come close to another significant tournament win.

It has been 10 years since Nalbandian made the Wimbledon men's final in 2002 at age 20. Since then, he has never made it past the quarterfinals in six tries at the All England Club. 

His actions on the Queen's Club grass this weekend suggest that he'll be taken out in the first week of action at Wimbledon. He hasn't made it further than the third round since 2005.
