British police are investigating David Nalbandian for injuring a linesman while kicking an advertising board during Sunday's tennis final at Queen's Club.
Officials ruled that the Argentine had to default the match to Marin Cilic after smashing the sign - and the lineman's legs behind it - with his right foot.
Judge Andrew McDougal could be seen cringing in pain as the player sent part of the sign flying into his leg. Watch the video of his Nalbandian's outburst here:
McDougal was bloodied in the encounter but suffered no other injury. Nalbandian was leading 7-6, 3-4 at the time but was forced to default the match.
By doing so, he forfeited significant prize money and rankings points in the process ... all while injuring a linesman for no reason. Definitely worth it.
What's more, criminal charges may be in the offing.
"We are aware of an incident at the Aegon Championships on June 17," a Scotland Yard spokesman said. "A complaint has been made and the Metropolitan police service is investigating the incident. The allegation is of assault."
