Sunday's murder of his step-grandson won't keep former heavyweight boxing champ Joe Frazier from headlining an upcoming weeking of events at Bally's Atlantic City.

Though mourning the shooting death of Peter Lyde Jr., 25, stepson of his daughter, Philadelphia Municipal Court Judge Jacqui Frazier-Lyde, sources close to the pugilistic icon say he'll still headline the "Smokin' Joe Frazier's Sportzbox" extravaganza June 12-14. As a matter of fact, he's expected to spend Monday morning hyping "Sportzbox" on such outlets as Fox 29's "Good Day Philadelphia" and Michael Smerconish's morning-drive show on WPHT-AM (1210).

The weekend's "Main Event" will be the actual "Sportzbox" program on June 13. It's being described as a cross between "Hollywood Squares," "Family Feud" and a celebrity roast. Joining Frazier will be such luminaries as entertainer Joe Piscopo, 1950s pop superstar Bobby Rydell, former Miami Dolphins' placekicking star, Garo Yepremian and Vincent Pastore ("Big Pussy" on "The Sopranos"). It'll be bookended by a VIP cocktail reception June 12 and a June 14 golf outing. All three events--including the cocktail party (and its Red Carpet pre-show), which is being staged as a fundraiser for Gilda's Club, a cancer-related charity named in honor of the late "Saturday Night Live" star Gilda Radner--are open to the public.
