Mount St. Marys/Robert Morris -- Technical Foul Reversed

[VTOfficial]

At the 8:35 mark in the 2nd half, a MSM player steals the ball and dunks it on the fast break. The Lead official calls a technical foul for hanging on the rim. The game went to commercial and when it resumed, the T-foul had been reversed and was not charged.

I didn't know you could 'take back' a T once it has been called? Is this in the rule book? Am I missing something?

If someone would like to post the video for discussion, you can.
