Top Rank Promotion chief Bob Arum warned Filipino ring icon Manny Pacquiao on the perils of being a fighter and at the same time being the promoter of his own fights.

Pacquiao, following the footsteps of former world champions Oscar Dela Hoya, Roy Jones Jr., and undefeated Floyd Mayweather Jr., is promoting his world title fight against World Boxing Association welterweight champion Lucas Matthysse on Sunday at the Axiata Arena in Kuala Lumpur, Malaysia.
