Warren Sapp -- Guilty In Hooker Case ... Cuts AMAZING Plea Deal

Warren Sapp has pled GUILTY in his Arizona prostitution case -- but he (probably) won't spend another day behind bars thanks to an INCREDIBLE deal he made with prosecutors ... TMZ Sports has learned.

We broke the story ... Sapp was arrested in Phoenix on February 2nd after admitting he paid 2 women $300 each to perform sex acts on him in his hotel room. Sapp was charged with solicitation and assault for allegedly roughing up the women after a fight over money.

Now, we've learned Sapp agreed to plead GUILTY to one count of solicitation and one count of assault and in exchange he must complete 2 counseling programs -- the first is a "Prostitution Solicitation Diversion Program" ... the 2nd is essentially an anger management course.

If Sapp FAILED to complete the prostitution program in 160 days -- he faced up to 30 days in jail.

The good news for Warren ... he already completed the program and the hooker charge will most likely be dropped.

As for the assault conviction, Warren is still working on completing that counseling program ... if he doesn't, he faces 30 days in jail and 2 years probation. But that's probably just a matter of time at this point.

Sapp has also been ordered to pay restitution to the two prostitutes ... $150 to Quying Boyd and $1,171.24 to Britney Osbourne.

All things considered, it's a GREAT deal for Sapp.
