With his Cleveland Cavaliers up big on the Atlanta Hawks, LeBron James attempted to sub himself out of Saturday's game after a play midway through the third quarter at Quicken Loans Arena.

The only problem with that is the referees never called for a substitution, meaning the Cavaliers were playing four-on-five basketball.

That's against the rules.

Cleveland's Richard Jefferson tried to hurry to check in for James, but he was not able to get into the game before play resumed. As a result, the Cavaliers were assessed a technical foul. Dave McMenamin of ESPN shared the rule that came into play:
