David Nalbandian subject of police investigation into alleged assault after injuring line judge at Queen's final The hoarding flew off its hinges and struck McDougall in the shin, causing an inch-long gash from which blood started to seep. Nalbandian was disqualified after being deemed guilty of unsportsmanlike conduct and he suffered further pain when he had his £36,500 prize money withdrawn and heard he could be hit with a £6,400 fine. The Argentine apologised for injuring the line judge during the post-match presentation and later he reiterated his remorse on Twitter. I am sorry and remorseful for what happen in today's Queen's final. I had not intention of hitting the linesman and it was an unfortunate reaction to the loss of a point. I had the opportunity to apologise in person. I realise this was a very regrettable incident. Finally I apologise to the public, the director of the tournament and my fans and followers in Argentina and around the world. However, he also did hit out at the ATP for the "pressures" the calendar puts on players's workloads. Yet despite the incident, Nalbandian hopes to return to the Wimbledon warm-up event next year. "This incident doesn't mean that I'm not going to come back," Nalbandian said. It doesn't matter. I really feel good at this tournament. The tournament director is great to me and I like it. This is a bad situation for everybody and I really apologise for that but it doesn't mean anything to next year. The 6,000-strong crowd sided with Nalbandian straight after the incident, many of them unaware the kick had caused such damage to the left leg of McDougall, who needed treatment for the injury. Tournament director Chris Kermode stopped short of saying the 10th seed would definitely be allowed back, but conceded banning the player would be highly unlikely. "Look, mistakes happen," he said. I haven't really thought about next year, but you can ask me again in a couple of weeks There was no way he intended to do that. It would be foolish to say he's not welcome back to this tournament. The tennis he's played this week has been phenomenal and the crowd like him. You could tell by the crowd that they wanted him to play, so, you have to forgive these things and move on.
