DETROIT (AP) — It’s Showtime in more ways than one for Floyd Mayweather Jr., who is excited about both a weekend fight he’s promoting as well as his lucrative new deal with the CBS-owned network.

Mayweather was in Detroit on Thursday for a news conference ahead of Saturday’s junior middleweight bout between Cornelius Bundrage and Ishe (EE’-shay) Smith. Mayweather likened his new Showtime agreement to a matrimonial modification.

Recently divorced from fight king HBO, a smiling Mayweather told reporters he’s “married again.”

The sport’s biggest star and moneymaker announced Tuesday that he’ll fight Robert Guerrero on May 4 on Showtime, a move that shook up the boxing universe.

Mayweather’s Showtime deal could include up to six fights over 30 months. The Michigan native turns 36 on Sunday.
