A day off didn't mean a day of rest for Florida Georgia Line's Tyler Hubbard. The long-haired half of the hit country duo got muddy on a dirt bike on Sunday (Feb. 16) after finishing up a weekend of tour stops. Unfortunately, the afternoon of fun didn't end well for him.

FGL's Brian Kelley shares that Hubbard hit a jump a little short, injuring his back. He's been in excruciating pain since. This week, he has already visited with two chiropractors and gone to the hospital, so he's on rest ... at least until the Night Train Tour resumes this weekend in Grand Rapids, Mich.

"He's no Evil Kinevil," Kelley said, joking about Hubbard's injury but wishing him well alongside a few hundred radio and music industry personnel during an event at Country Radio Seminar on Tuesday night in Nashville.

The room raised shots of Fireball Whisky in Hubbard's honor.

The duo was scheduled to play, but pulled out of the show because of Hubbard's injury. Earlier in the day, the singer was visibly uncomfortable while participating in media events. Tim McGraw, Rascal Flatts, the Cadillac Three and the Eli Young Band took the stage, playing a mix of familiar hits and brand new music.
