There are a couple of interesting bouts on tap this weekend with Nicolay Valuev defending his WBA heavyweight title against former cruiserweight champ (and current loudmouth champ) David Haye in Germany, and undefeated Chad Dawson in a rematch with 40-year-old Glen Johnson in Hartford, CT. Dawson scored a 12-round unanimous - but tougher than expected - decision over Johnson last year.

Elsewhere, Zab Judah and Joel Casamayor return to action on Friday night on the same card in Las Vegas - but not against each other.

Finally, did you happen to catch Manny Pacquaio on the Jimmy Kimmel Show last night? If not - and you'd like to see Pacman sing - then check this out:

At first it appeared as if Manny was being set up to embarass himself, but not to worry - even though English is not his primary langauge, he's already better than other boxer-singer wannabes like Joe Frazier and Larry Holmes.

Showtime doesn't track punch stats but if they did, last night's IBF bantamweight title fight between champion Joseph Agbeko and undefeated challenger Yonnhy Perez likely would have set a new record for a 12-round bout. Every round had non-stop back-and-forth action as both men demonstrated great conditioning, skill and desire. An unintentional clash of heads opened up a pair of cuts on the forehead of Perez but he was never hindered by the damage. In round ten, another clash of heads sent Agbeko to the canvas but referee Robert Byrd ruled it a knockdown. Fortunately, that mistake didn't determine the outcome of the fight as all three judges scored the fight for Perez: 116-111 and 117-110 twice. If you missed the fight, try to catch a replay on Showtime - you won't be disappointed. A rematch is likely.

In the co-feature, rising star Antonio DeMarco floored Jose Alfaro three times in round ten to score a TKO win and capture the WBC interim lightweight title. DeMarco was ahead 90-81 and 89-82 twice on the scorecards at the time of the stoppage. Next up for the 23-year-old DeMarco may be a bout with undefeated WBC lightweight champ Edwin Valero.

Between bouts, Mike Tyson and promoter Don King publicly reconciled in an interview with Showtime's Jim Gray. Gray mentioned George Foreman winning a title at age 45 and asked if Tyson, 43, might consider a comeback. Tyson seemed to be joking as he answered "I'm not really considering doing that ... I'm so fat and out of shape ... If he [referring to King] is going to pay me for my training team, my training team costs a lot of money ... Anything's possible ... This guy is capable of making a lot of things happen. I don't see it happening, but you never know with this guy". As far-fetched as it may seem, the entire interview seemed staged by Showtime and King to begin the process of persuading Mike Tyson to fight again. It's a horrible idea but King and Showtime would definitely profit from such a comeback so don't doubt for a moment that they're actively working to convince Tyson otherwise. Do you really think either Tyson or Evander Holyfield could say no to the payday that Tyson-Holyfield III would provide?

Old heavyweight fighters never really retire ...they're just between bouts.

This past weekend, 41-year-old Andrew Golota was TKO'd in five rounds by Tomasz Adamek, who moved up from cruiserweight for the big fight in Lodz, Poland. Golota has now dropped four of his last seven bouts - including three stoppages - but is unlikely to retire.

Elsewhere, Oliver McCall, 44, scored a ten-round unanimous decision over Lance Whitaker, 37 in Las Vegas, and Frans Botha, 41, fought to a majority draw against Pedro Carrion, 39, in Dessau, Germany.

43-year-old "King of the Four Rounders", Eric "Butterbean" Esch, recently returned to the ring after more than two-and-a-half years and lost a four-round split decision to 46-year-old Harry Funmaker, who hadn't fought in nearly four years! After the bout, Butterbean announced his retirement. Don't believe it ...

Other past-their-prime heavyweights preparing for upcoming bouts include John Ruiz (37), Hasim Rahman (36), Michael Grant (37) and Oleg Maskaev (40). See complete schedule for details.

Four fighters defended world title belts last night: Juan Manuel Lopez and Yuriorkis Gamboa at Madison Square Garden in New York, and Jorge Linares and Toshiaki Nishioka in Tokyo, Japan. Only three were successful . . .

Also, pound-for-pound top ten Israel Vazquez - finally healthy again after back-to-back-to-back wars with Rafael Marquez - returned to the ring for the first time in 19 months.

Fighting for the first time in two years (and only the eighth time in the last 6-1/2 years), heavyweight David Tua (50-3-1) stopped Shane Cameron (23-2) in two rounds in Hamilton, New Zealand. Tua showed he hasn't lost his power, knocking Cameron down twice in the first round. After the second knock down, Tua landed a left and a right after Cameron was already down and was fortunate not to be penalized (or possibly even disqualified). In round two, Tua immediately landed 13 unanswered shots, knocking Cameron down a third and final time and forcing referee Bruce McTavish to stop the fight only seven seconds into the round.

Tua, who early in the 1990s KO'd John Ruiz, Oleg Maskaev and Hasim Rahman, has squandered what once looked like a promising career with inactivity and poor conditioning. He reportedly shed nearly 60 pounds to get down to 238 for this bout. Nevertheless, Tua is still only 36 and, if he's finally serious about his career again, his one-punch knockout power could make him an interesting opponent for anyone (not named Klitschko) in the heavyweight division.

On May 22, 1993, Roy Jones Jr. scored a unanimous decision over Bernard Hopkins (116-112 on all three cards) to win the vacant IBF middleweight title. A rematch has been discussed for the past 16 years ... now it looks like it will finally happen - when the two future Hall of Famers will be a combined age of 86!

Contracts for the rematch have been signed by both fighters with a target date of early 2010. The contract calls for a 50/50 split with a reported 60/40 split in the unlikely event the winner scores a KO or TKO.

Hopkins has discussed a Dec. 2 tune-up and Jones is currently slated to face Danny Green in Sydney, Australia on that same date. Don't bet on either man risking the big money attached to the rematch with a meaningless bout in the interim.

The Sept. 19 bout between Floyd Mayweather Jr. and Juan Manuel Marquez exceeded expectations with one million pay-per-view buys. The $52 million in PPV revenue makes it the highest-performing event of 2009 and only the fifth non-heavyweight event to reach one million PPV buys. Mayweather's 2007 win over Oscar De La Hoya still sits atop that list with 2.44 million buys.

The Nevada State Athletic Commission reports that the live gate for Mayweather-Marquez was $6,811,300 on ticket sales of 12,009.

Imagine how much money Mayweather vs. Manny Pacquaio would generate ...

At 38, an age when most boxers are in decline (if not retired), WBC heavyweight champ Vitali Klitschko, looked better than ever. At 28, previously undefeated Chris Arreola demonstrated a solid chin and an undeniable desire to win but little else to back up Larry Merchant's label as the "most promising American heavyweight since Riddick Bowe".

Klitschko, fighting with his hands by his sides, countered Arreola's aggressive style with clean, effective shots throughout the bout. Unlike many recent opponents of both Vitali and brother Wladimir Klitschko, Arreola never quit and, despite being bloodied and battered, was never in any real danger of being knocked down. Nevertheless, after ten one-sided rounds, Arreola’s trainer Henry Ramirez had seen enough and mercifully instructed referee Jon Schorle to stop the fight.

Scoring: All three judges had Klitschko well ahead at the time of the stoppage: 100-89 and 99-91 twice.

Punch Stats: Total Punches: Klitschko - 301 of 802 (38%), Arreola - 86 of 331 (26%); Total Power Punches: Klitschko - 151 of 283 (53%), Arreola - 24 of 107 (22%).

Next up for Klitschko may be a December date with 30-year-old Kevin Johnson (22-0-1), another "promising American heavyweight" whose lack of KO power will make him an even longer shot to upset Klitschko than Arreola. As for Arreola, his youth, personality and fan-friendly style (not to mention the lack of other quality heavyweights) give him a shot at being a heavyweight champ at some point in the future ... when both Klitschkos are retired and no longer dominating the division with relative ease.
