Olympic champion Anthony Joshua produced a devastating display as he continued an impressive start to life as a professional heavyweight with a first round stoppage of Matt Legg at Wembley.

Beginning the undercard to Carl Froch's world super-middleweight rematch with George Groves, Joshua shone brightly in front of a half-full stadium in what has been a fleeting introduction to professional status since April last year and carded victory number six just one minute 23 seconds into the opening round.

The pair both featured on the Prizefighter show last November, after which Legg admitted he had spoken to Joshua and said he saw him as a role model.

It was Legg who started sprightly after the first bell and landed the first meaningful blow, but Joshua stood firm and made his impressive reach count. A fast, four-punch combo from Joshua provided the first roar of the night from the north London crowd.

Legg attempted to respond, but Joshua proved far superior. A heavy right uppercut was simply too much for Legg, who fell to the canvas after his opponent's crushing blow.

He did not survive the count and Joshua claimed his sixth professional victory, all of which have come within the first two rounds, to retain his unbeaten status. A fight with former world title contender Matt Skelton in July appears to be next for the 24-year-old.

Jamie McDonnell claimed the vacant WBA bantamweight world title with a 10th round knockout of Tabtimdaeg Na Rachawat.

McDonnell was forced to work hard for his victory. Nine rounds passed and, although McDonnell appeared comfortably clear on the scorecards, the Wembley crowd sat distinctively quiet with no sign of a fight-winning punch in sight.

McDonell landed a superb body shot in the sixth and quick one-two combo in the seventh, but Na Rachawat was not visibly fazed by either exchange.

Indeed, the punch that earned McDonnell the title came in round 10. Na Rachawat was so busy trying to put pressure on his Doncaster opponent that he left his chin wide open; McDonnell took full advantage off the ropes and floored him with a vicious left hook.

Na Rachawat's first fight outside of his native Thailand ended with his third professional loss while McDonnell, who was stripped of his IBF belt in October last year, had his arms raised as a world champion for the second time in his career.

Kevin Mitchell produced a remarkable comeback to knock out Ghislain Maduma in what should have counted as an IBF lightweight championship eliminator.

The winner was due to earn a shot at champion Miguel Vazquez, but Mitchell weighed in 12lbs over the limit earlier on Saturday. As a result, a bout with Vazquez is now unlikely for the Dagenham fighter.

Maduma was previously unbeaten in 16 professional bouts and unleashed early pressure on Mitchell, who was caught heavily on the jaw in round three. The Brit was subject to more punishment in the fourth and had to retreat in the corner to hold off his opponent.

Mitchell looked shaken from a big right in the ninth but Maduma did not hold up in round 10; after being caught with a huge right, Mitchell signalled to his corner about his jaw.

However, Mitchell's fight remained intact. He started round 11 with a quick combo which had both Maduma and the crowd rocking. The Canadian continued to stumble under pressure from Mitchell, who completed victory with a superb left. Maduma fell as the crowd rose and the fight was stopped.
