Dolph Ziggler claimed that actor Hugh Jackman broke his jaw with that punch on Monday's RAW.
However, wrestling journalist Dave Meltzer revealed this in his news update today:
Regarding the Hugh Jackman/Dolph Ziggler stuff, the broken jaw thing is a work. Ziggler was fine after the show. They just decided to work an angle off it for publicity. And it got publicity, including on the Early Today show on NBC where they covered it like Jackman had broken his Ziggler's jaw.
