De La Hoya: I Feel 'Very Confident' Pacquiao-Matthysse Happens
There has been a lot of reports of the fight between Manny Pacquiao and Lucas Matthysse, scheduled for July 14th in Malaysia, not taking place as there are some financial issues plaguing that event.
Golden Boy Promotions and Matthysse had been waiting on some money due to them the past few weeks.
https://www.boxingscene.com/de-la-hoya-i-feel-very-confident-pacquiao-matthysse-happens--129425The reports seems to point to MP promotions unable to provide the needed money and a shortage of $2M in financing. I honestly believed that this is just a ploy to attract boxing fans specially in the US to buy the PPV, sort of marketing.
Mattysse already received his money and on his way to Malaysia as reported:
t took longer than promised but Golden Boy Promotions and Lucas Matthysse have received their funds from the organizers of the July 14th event in Kuala Lumpur, Malaysia.
So with that said, Matthysse and his crew will be flying out there for his scheduled date with Manny Pacquiao on Tuesday.
"We have a fight, everything's great, everything's perfect," confirmed Eric Gomez, the president of Golden Boy, on Monday afternoon ."They're flying out tomorrow, we're looking forward to it. Lucas is ready and he's ready to defend his title against a legend."

Its only about 10 days to go and I hope that Lucas can acclimatized himself on a hot weather in Malaysia. As for Manny, no adjust needed because Malaysia and the Philippines have the same weather (almost).
