Jacksonville Jaguars' star running back Leonard Fournette got into a heated exchange with a heckler in Tennessee on Thursday, threatening to whoop the fan's ass in front of everyone.

As seen in the video embedded below, Fournette challenged someone in the crowd to come down on the field before team personnel intervened. Still, he continued jawing with the heckler from the bench.

"Facts, you're too old for that," Fournette told the fan during the Jaguars’ 30-9 loss in Tennessee. "You're too old for that. Chill out. I'm not worried about you. You want to come down here?? I'll whoop your ass."

Fournette, 23, was suspended for the Jaguars' Week 13 game against the Indianapolis Colts for his role in the Jaguars-Bills brawl the previous week. Following that incident, he issued an apology thru social media which reads, "Would like to apologize to my team, fans, and kids at home who look up to me, things got heated in a very important game emotions got the best of me again I apologize and this loss is on me thank you."

It remains to be seen if he'll face any punishment for his interaction with the fan in Tennessee - but it won't make much of a difference either way as far as the Jaguars' season is concerned. After reaching the AFC Championship game last season, the Jags are now sitting in last place in the AFC South with a 4-9 record. They'll host the Washington Redskins in Week 15.
