Andrew Flintoff likely to quit boxing after controversial heavyweight win over Richard Dawson "I know that I gave it everything I have and it has worked out well for me, when it might not have done," Flintoff said. You have to work at anything in life. This has given me the drive and determination to apply to whatever I do next. Whatever that is, I know now I can push on and when it gets tough I can plough through. Flintoff, 34, overcame American Richard Dawson at Manchester Arena on Friday night, surviving a second-round knock-down to win a narrow points decision. In an interview in the Manchester Evening News, he said: "I proved a lot of things in this fight, I have had a few personal battles, and every time I walked through the ropes during training it has been a battle. Some of the criticism I can understand, people want to respect this sport, that's fine. But some of the cheap swipes I can't be bothered with. This was never about degrading boxing. We wanted to do it properly and show boxing for the fantastic sport it is. At times boxers don't get the credit they deserve, Martin Murray, 30, will face Sergio Martínez for the World Boxing Council middleweight title in Argentina on April 27. He is the third British middleweight - after Darren Barker and Matthew Macklin - to challenge the Argentine for the world title in the past two years. Martínez, 37, stopped both challengers in the late rounds. The St Helens fighter, part of Ricky Hatton's promotional stable, has been rewarded for his win over Jorge Navarro last month when he won the World Boxing Association interim belt. Murray's previous world-title shot ended in disappointment when he controversially drew with Felix Sturm in 2011 in Germany.
