Paulie Malignaggi suffered concussion in loss to Shawn Porter

Former two-division world titlist Paulie Malignaggi is out of the sport for the time being, as the 33-year-old veteran suffered a concussion last Saturday night in his TKO-4 loss to Shawn Porter on Showtime.

Malignaggi (33-6, 7 KO) will still be on the call on May 3 for Showtime pay-per-view's big Mayweather-Maidana bill, however, and may be very close to being a full-time commentator, with his in-ring days seemingly near an end.

"I am feeling very good at this stage, but anytime you have any level of concussion, your best bet is to fully recover before doing virtually any activity," Malignaggi said in a statement. "There will be plenty of action on Saturday and the audience will be in good hands with Danny on the stick. But make no mistake: I will not miss next week's event in Las Vegas. I have been looking forward to that fight card for some time. I'll be ready."

Malignaggi will not call this weekend's triple-header, however, and will again be temporarily replaced by Daniel Jacobs, who made his commentary debut last weekend with Malignaggi in action. This Saturday's show is a triple-header featuring Keith Thurman vs Julio Diaz, Lucas Matthysse vs John Molina, and Omar Figueroa vs Jerry Belmontes.
