Former G-Unit rapper Young Buck has accepted Tony Yayo's challenge to a fight.

Late last month, Yayo appeared on the Russ Parr radio show saying he wanted to exchange blows with Buck.

Buck responded to Yayo’s challenge on XM satellite radio this weekend saying he would like to take it to the ring.

“I’ll do it,” Buck said.  “I’ll do it off of real nigga shit I swear on my child’s life.  If they line this shit up, where me and that nigga can go in a ring, we can put that shit on VH1.  We can make that shit real life.  I’ll have Floyd Mayweather training me.  I’ll knock that nigga’s fat, flabby, old non-rappin’ ass out.”

As reported earlier, 50 Cent ousted Young Buck from G-Unit after the Memphis bred rapper began distancing himself from the group and claimed he hadn’t been paid for his work with G-Unit.
