Allen Iverson to Return to BIG3 League Despite Blowing Off '17 Game

It's all water under the bridge for Allen Iverson and the BIG3 basketball league -- we're told the NBA legend will RETURN after a rocky 2017 season.

Iverson -- who was a player coach last season -- was in the BIG3 dog house after no-showing for a game without a reason. He was suspended 1 game.

It seemed his future with the league may have been in doubt at the end of the season -- but now we're told he WILL get another go ... this time as a coach only.

One of Iverson's issues ... he gambles A LOT. He was spotted out in a casino in almost every city he traveled to during the BIG3 season and there are concerns the gambling could have interfered with his commitment to the league.
