Boxing:Iron Mike Tyson takes on the little mermaid in Copenhagen this weekend. Just that this little mermaid happens to be the 6'3" Brian Nielsen. The fight though is expected to just be an appetizer for Tyson, as he readies himself for a bigger battle. Tyson, a former heavy weight champion, is in Denmark for a fight against Nielsen on Saturday. The two fighters appeared together for the first time on Sunday to promote the fight. Tyson, 35, has been idle for almost a year. He last fought Andrew Golota in October 2000. But that turned out to be an easy one for Mike, after Golota retired after the second round. And he is looking forward to what many are calling a Danish pastry in Copenhagen. But the tall Dane isn't as easy meat as he's made out to be. He has 43 knock-outs from 62 matches, with just a single loss. The 36-year-old feels he is the best shape of his life and will give Tyson a tougher time than the American has had in his last three fights. Tyson's last three fights have lasted just over 10 minutes in all. "I don't think he has the same energies that he had before. He still has the punch, but I don't think he has the heart that he had before," felt Nielsen. Tyson though knows that this fight is just a small stepping stone to the overall objective. That of course will be the possible chance of taking on the winner of the fight this November between Lennox Lewis and current world heavyweight champion Hashim Rehman.
