TNA Wrestler -- FINED Over Unscripted Crotch Thrust on Female Announcer

TNA wrestler Austin Aries was hit with a "severe fine" by the organization this week after he went off the script during a recent live event and shoved his man bits into a female announcer's face, TMZ has learned.

The unscripted crotch-thrusting went down earlier this month on "Impact Wresting" ... when Aries became upset at announcer Christy Hemme for calling him the wrong name during his ring intro.

Hemme was clearly upset during the junk attack ... and afterward, she even tweeted about the incident ... calling it "unacceptable."

But sources tell us ... Aries -- real name Daniel Solwold, Jr. -- reached out to Hemme and privately apologized, acknowledging he crossed the line.

TNA also came down hard on Aries and slapped the wrestler with a fine -- it's unclear how much cash Aries will have to fork over.

As for Hemme, we're told she has spoken with TNA officials and told them she was "satisfied" with Aries' apology.
