Should boards/commissions publicize medical statements in case of a pull out?

Don Charles, the trainer of Derek Chisora and Wadi Camacho, recently sat down with me and talked over the issues of fighters pulling out of fights without providing the opposing team with adequate medical statements. Amongst other things, Charles noted that most of the times boxers pull out of fights, the opposing team and the board/commission are never given adequate evidence that the fighter is really injured. Of course, the recent example of this would be David Haye who pulled out of three different dates in 2013 (one was supposed to take place in February, 2014) - without providing the opposition (Manuel Charr, Tyson Fury twice) with any medical statement. Another example was, of course, when Wladimir Klitschko pulled out on Derek Chisora twice - only to subsequently schedule a fight with then WBA heavyweight champ, David Haye. “It’s happened to us personally – me and Dereck Chisora – where we’ve gone to camp, spent a large amount of money paying sparring partners and mentally preparing ourselves only for that opponent to suddenly pull out with an injury. How come we never can challenge it? "I have never seen any medical evidence of these injuries from governing bodies, officials, managers or promoters. “I think all of these things should be made public because it is the public after all that are supporting it publically. Therefore, it is in the public interest.” It is an interesting topic, as most fighters are either independently managed or promoted with little-to-no requirements given to them by their commission or board. Charles proposed to me that when signing a fight, both boxers should also sign a petition with the board to ensure if any injures occur without proper medical evidence, the pulling out fighter should cover the costs of the other man's camp (if a rematch is not scheduled). What are your feelings on this and how would you want it changed?
