Rascal Flatts has responded to reports of an attack at their Charlotte, N.C., concert over the weekend.

NASCAR veteran Mike Wallace says he and his daughter were attacked by three men after the show on Friday night.

Nathan Lucas and Randolph Mangum were charged with assault Saturday morning and a third man, Paul Lucas, was charged with assault on a female, according to the Charlotte-Mecklenburg Police Department.

Wallace told WSOC-TV that as he was leaving the concert, he saw a man in a truck screaming. He asked him what was wrong and the next thing he knew he was "getting punched in the face."

In 2014, following a string of alcohol-related incidents at country concerts, Rascal Flatts' lead singer Gary LeVox told FOX411 Country "these sort of things happen periodically every year and normally in the summer time.

"I think when you're outside in the heat and people are out drinking and listening and having a good time, I think they don't know when to shut it down before it's too late."
