Rooney knocked out!

Manchester United star Wayne Rooney has found himself embroiled in a bizarre incident after footage emerged of him being knocked out by former team-mate Phil Bardsley in an impromptu boxing match in his kitchen, apparently on February 22.

Rooney was sent sprawling after Bardsley jabbed him with his left hand as they indulged in a friendly sparring bout.

The 29-year-old England skipper is seen falling to the floor and appears to hit his head on the ground.

He was left apparently out cold, arms splayed to the side and his head partially under a dining room chair. As he lay unconscious, shocked friends rushed over before filming came to an end.

The footage could see Rooney find himself in hot water both with his club and with England manager Roy Hodgson.

The tussle could have left Rooney with serious injuries and many medical experts have advised Rooney to get an MRI done for his own health and well-being.
