GAVIN Whyte will be warned of his future conduct by Oxford United today after a lewd video of the winger appeared online.

A film of the 22-year-old from the weekend was leaked last night, which Northern Ireland manager Michael O'Neill described as "clearly unacceptable".

The video emerged shortly after Whyte won the George Best Breakthrough Award at the Belfast Telegraph Sports Awards.

In a statement from the club, boss Karl Robinson said: "It is totally out of character.

"Gavin is a quiet, respectful young man who is totally devastated by this: I have rarely heard anyone so remorseful for something that he regrets and knows he shouldn’t have done.

"Clearly he had drunk too much, and we will deal with that too, but whether you are a footballer or not that sort of behaviour is wrong on every level.

"We will sit down with Gavin today and we will remind him in no uncertain terms of his responsibilities.

"We have psychological and behavioural support here to help him get through this.

"He is a great kid and I hope the fans can forgive him for one moment of madness.”

The winger, who has since deleted his Twitter account, has been one of United’s stand-out players this season, after making the move from Crusaders in July.

He has scored six times for Karl Robinson’s side and netted with his first touch in international football, against Israel in September.

Northern Ireland's O'Neill said: "Gavin's actions in the video are clearly unacceptable and fall far below the standards that we expect from a Northern Ireland international.

"I know that Oxford United will discipline him appropriately for this significant mistake and both his club and the Irish FA will put in place measures to make sure that he learns from it."
