The Game -- I'd Beat the F**k Out of George Zimmerman

The Game will throw his hat in the ring to fight George Zimmerman in the upcoming celebrity boxing match, and he tells TMZ, "I will beat the f**k out of him."

Zimmerman has agreed to the March 1 celebrity boxing match ... the promoter hasn't selected his opponent, but is taking offers at fightgeorge@hotmail.com.

Game says, "I would not be boxing for me. I'd be boxing for the legacy of Trayvon Martin and for his family."

The rapper, who has a tattoo of Trayvon on his leg, says, "I would box him to knock him out," adding, "I would definitely take pleasure in it. It's legal, and I want to show him you can solve your disputes without a weapon."

Game would definitely have the edge ... he's 6'5", and 240 lbs of muscle.
