Juan Manuel Marquez stands to become the highest-earning Mexican fighter in the event a fifth fight with Manny Pacquiao takes place in 2013, a fact that should force Marquez to postpone his retirement party to a much later date.
Marquez's stature received a major boost following his sixth-round knockout of Pacquiao last Dec. 8 and Fernando Beltran, Mexico's premier promoter, said only a clash with the Filipino can bring him a paycheck no other Mexican, including the legendary Julio Cesar Chavez Sr., has received.
In the fourth fight with Pacquiao, the 39-year-old Marquez got $6 million plus a share in the pay-per-view.
Pacquiao was guaranteed $23 million and also a slice in the PPV.
Chavez, in contrast, received his biggest purse - said to be $9.1 million - when he faced Oscar De La Hoya in June 1996.
Although Arum hasn't formally reached out to the camps of Pacquiao and Marquez about the staging of a fifth fight, saying he will only do so after the holidays, reports have started to swirl that the massive Cowboys Stadium in Dallas, which can seat more than 80,000, is the frontrunner to host it.
The MGM Grand Garden Arena can only accommodate 17,000 for a big fight.
Still, Arum said Pacquiao has to get clearance from US doctors first before he can be allowed to return to the ring owing to the devastating knockout that he suffered at the hands of Marquez.
Arum wants Pacquiao, 34, to undergo a battery of tests that will be done at the renowned Cleveland Clinic, a brain center in Las Vegas.
A September date is being targeted as Pacquiao's comeback bout because he is being advised to take a lengthy rest since he is not allowed by the Nevada Athletic Commission to fight in the next four months.
The Nevada commission also prevents Pacquiao from engaging in sparring sessions in the next three months.
