Rapper DMX has been named George Zimmerman's opponent in his upcoming celebrity boxing match.

Celebrity boxing promoter Damon Feldman tells TMZ DMX was selected out of 15,000 applicants.   Zimmerman issued the open challenge to fight anyone.

DMX promised to "beat the living f**k out" of Zimmerman in the ring.   Zimmerman shot and killed Florida teen Trayvon Martin (claiming 'stand your ground' laws).

 
Zimmerman has been training for months.  He's only 30 years old. DMX is 43.

The boxing match will be 3 rounds.

The date, time, and location of the fight will be announced at a news conference next Wednesday.
