Allan Green says he feels like a new man following colon surgery.

That might mean major problems for Sherwin Davis when the pair meet tonight in a super middleweight fight at the Buffalo Run Casino.

Green had 85 percent of his colon removed during surgery two days after a first-round knockout of Darrel Woods here in July.

“My colon was paralyzed, Green said. “I hadn't been healthy for almost 2 1/2 years. I feel great now.

“My body isn't retaining those toxins, fluids and wastes, said Green, noting that he lost about 16 pounds after the surgery. “I haven't felt this good in three years.

He was hospitalized for 10 days after the surgery. Green started running again a week after his discharge, then resumed training the following week.

“Sick was not the word, Green said. “I felt terrible in camp (during preparation for a March HBO fight against Edison Miranda). Tony was going to pull me out of the fight in the dressing room. As a fighter, you believe in the back of your mind that you can catch him with something, which I did, but I didn't have enough gas to finish him off.

Green wound up suffering his only professional loss, dropping a unanimous decision to Miranda.

“I don't worry about it - I will be world champ in '08, said Green, who is 24-1 with 17 knockouts.

The 33-year-old Davis is 18-5 - all five coming in his last six outings.

Davis, of Indianapolis, is best known for spoiling the undefeated record of 2000 United States Olympian Dante Craig via a third-round TKO.

This will be Green's first outing here since a sixth-round TKO against Donny McCrary on April 26, 2006.

Six of his previous seven outings had been at Buffalo Run.

“It's great to have Allan back, said promoter Tony Holden. “It's rare that he gets to fight here because he's become such a national star. He's getting all types of offers from Vegas and Atlantic City.

Green and Holden are divided on how long the match should last.

“I expect it to be quick, Green said. “I'm not going to say first round. I wouldn't like the fight to go past four. I want to take care of business and move on.

Says Holden: “I would love to see five or six rounds so he could get some work in. For his career, a one-round knockout would be great, but for me, as his promoter, I would like for him to get some work in and take a good look at him.

Wahib Raheem, brother of former world title challenger Zahir Raheem (who had been in Holden's stable), will make his professional debut in a junior lightweight bout.

Action starts at 8 p.m. The fights will not be televised.
