Amir Khan's career came to a shuddering halt with a brutal fourth round stoppage at the hands of unbeaten American Danny Garcia. In a packed Mandalay Bay hotel in Las Vegas, Khan started well with Garcia seeming to have no answer to the speed Amir was bringing to the table. Khan caught Garcia in the 2nd round, opening up a nasty cut just above the American's right eye. Coming out for the 3rd Khan must have been confident he had Garcia's number, but that all changed with a great shot from no-where. It knocked Khan to the canvas and whilst the Brit bravely got to his feet he was on wobbly legs. He somehow managed to see the round out, but look 'spaced out' in his corner. He got up for the 4th round and seemed to have recovered somewhat. However, Garcia sensed blood and every shot landed seemed to have an impact every-time he landed. He sent Khan to the canvas again and when a shot hit Khan's forehead the fight was over. Khan said afterwards he felt he could of continued, but most felt he could have few complaints. Garcia now has the boxing World at his feet, 24-0 and only 24 years old. Where now for Khan? A fight against Kell Brook may be on the horizon - but no chance of a shot at Floyd 'Money' Mayweather anytiem soon.
