YouTube stars Austin McBroom and AnEsonGib will have to wait a bit longer to duke it out in the ring -- the Social Gloves boxing event has been postponed, TMZ Sports has learned.
We're told the fight date has been pushed back to early September due to Gib not being medically cleared to participate over a head injury.
As we previously reported, the whole event -- which also featured NFL stars Adrian Peterson and Le'Veon Bell -- was at risk of being scrapped ... but thankfully, the organizers were able to come up with a solution and salvage things.
