Uusally if a fighter got dominated and then quit I dont think he would be deserving of a rematch under normal circumstances.
This one is an exception though as despite his terrible effort he did meet all Wards demands to make the fight happen so Andre should return the favour as he should have with Mikkel Kessler. However unless theres something in the contract I dont think ward would ever take it. I dont like Dawson but he took a risk and it wouldnt have happen if he didnt take risks. He should be rewarded by getting a return rather than punished for trying to break the mould of only defending in fights guaranteed to win and not taking risks.
