Luke Bryan is not here for crude behavior.

While performing for the Volunteer Jam at Nashville's Bridgestone Arena on Wednesday night, the 40-year-old country singer took a swing at a heckler in the front row after seeing him gesturing with his middle finger. Bryan was in the middle of singing his latest hit, "Move," when he paused briefly to make his way down to the audience, hit the man with a right hook -- microphone in hand -- and return to the stage to finish the song. Immediately after the incident, security descended on the heckler and removed him from the venue.

The moment was captured clearly by concertgoers from multiple angles and posted to social media, though Bryan has not personally addressed the incident on his accounts.

"A man in [the] front row was making crude hand gestures toward Luke during his performance," the singer's rep tells ET in a statement. "It was insulting not only to him, but more importantly to the men, women and families sitting around him who were there to support and celebrate Charlie Daniels and the efforts of raising money for the military veterans – some of who were in the audience. The concert security personnel saw the man's disruptive actions of the event and he was escorted out."

Looks like Bryan's clavicle is on the mend after suffering a fracture in October! The superstar was injured just before kicking off his Farm Tour, where he joked that the best remedies for a broken bone are whiskey and "East Tennessee moonshine."

Earlier this year, just before ringing in his 40th birthday, Bryan opened up to ET Canada about his hopes and dreams for the next 40.

"I think the day you don't wanna roll the dice on something or go a little bit outside of your norm, I think that's kinda when you get a little stagnant in this business," he said of his career. "The main thing for me is just to focus on enjoying [life] and being happy and trying to be a better singer and writer, every day."
