LOS ANGELES — Mike Tyson showed glimpses of his destructive prime Saturday night during the 54-year-old boxing icon’s return to the ring for a lively exhibition bout with 51-year-old Roy Jones Jr.

Both fighters had impressive moments during a fight that was unofficially ruled a draw by the WBC judges at ringside. Tyson and Jones fought eight two-minute rounds, and both emerged smiling and apparently healthy from a highly unusual event at Staples Center.

Tyson tagged Jones with body shots and a handful of head punches during a bout that was required to be a fairly safe glorious sparring session.
