Floyd Mayweather Jr. has been ordered to stay away from his baby mama Josie Harris and their two children ... as a result of a domestic incident back in September.
The boxing champ was not present at the Clark County Courthouse in Las Vegas where the judge issued the ruling.
As we previously reported, Floyd's baby mama Josie Harris claims the boxer beat her up, threatened to kill her and stole her cell phone on September 9.
The judge set Floyd's bail at $31,000 -- and stated that she did not believe he was a flight risk.
Floyd is due back in court in January.
