Roy Jones Jr. to headline boxing/MMA card

It's the closest you'll see Roy Jones Jr. in a mixed martial arts card. The former boxing champ will headline a boxing/MMA card on March 21 in Pensacola, Florida.

Jones Jr. will fight Omar Sheika in a light-heavyweight boxing bout, ESPN confirmed today.

Jones Jr. had spoken about going head-to-head against UFC middleweight champ Anderson Silva, but only in a boxing fight. Both parties wanted the fight but the UFC didn't want to accept the risk of one of its top stars today losing to the aging legend.

The card being promoted Jones' Square Ring company will feature mixed martial arts fights to be announced.
