Apparently, there's still money to be made in boxing -- because Sugar Shane Mosley, the likely next opponent of Manny Pacquiao, pulled $650,000 per MONTH in 2010 ... this according to legal documents filed in his divorce case.

Mosely was just ordered to pay his soon-to-be ex-wife Jin Mosley a whopping $20,000 per month in support starting this month ... plus he's got to shell out an extra $60,000 for the past three months.

According to the docs, filed in Los Angeles County Superior Court, Jin claims she needs the cash to pay for several monthly expenses like:

-- Clothes ...........................................................$5,073
-- Jewelry .......................................................... $1,666
-- Cosmetics, beauty ........................................... $2,000
-- Massage therapist ........................................... $360
-- Personal trainer .......................................... .... $720

The couple was also ordered to sell their Southern California mansion ASAP so they can divvy up the cash from that deal.

Mosley did get one minor victory -- the judge ruled he's allowed to keep his 2006 H3.

The man appreciates a good Hummer.
