Allen Iverson is officially out of Ice Cube's BIG3 league this season ... announcing he's stepping down from his coaching gig "due to scheduling conflicts."
"I have informed the @thebig3 that I will not coach this year and they support me in this decision," the Answer said in a statement on Wednesday.
"However, do know that this does not end my association or support of the league and I will attend games this season whenever able."
A.I. was suspended as a player/coach for 3's Company when he failed to show up to the Dallas stop on the BIG3 tour last season.
