Sources have advised BoxingScene.com that Tony Weeks will likely be the third man in the ring for WBO welterweight champion Manny Pacquiao’s third fight with Juan Manuel Marquez on Nov. 12 at the MGM Grand in Las Vegas.

The Nevada State Athletic Commission has yet to make a formal announcement, but all signs point to the veteran referee who has worked over 30 world title fights, the last one being Daniel Geale’s first defense of his IBF middleweight title against Eromosele Albert in Australia three months ago.

Weeks was the referee for two Pacquiao fights, a unanimous decision win over Marco Antonio Barrera in 2007 and the Filipino’s eighth-round stoppage of Oscar de la Hoya one year later.

He has also worked three Marquez bouts, the last being his wide decision defeat to Floyd Mayweather two years ago.  In addition, Weeks was on hand for Marquez’ 11th round stoppage of Joel Casamayor in 2008 as well as the Mexican’s points victory over Orlando Salido in 2004.
