Trace Adkins is headed back to the small screen for a guest appearance on NBC's The Night Shift.

Adkins, who has appeared on My Name Is Earl and voiced characters on King of the Hill and American Dad!, will be arriving at the show's San Antonio Medical Center injury free. TheWrap.com reports that the singer is set to play the head of an MMA veteran therapy group attended by Dr. TC Callahan, an ex-military serviceman, played by Eoin Macken, who has been dealing with PTSD this season.

The role fits in well with Adkins' real-life work with the military. He has performed on seven USO Tours, and he also serves as a spokesman for the American Red Cross and the Wounded Warrior Project, which helps veterans who are dealing with brain injuries.

Adkins has also appeared on -- and won -- NBC's Celebrity Apprentice, and he's set to be part of the cast of the upcoming Civil War miniseries To Appomattox, which stars Damien Lewis, who played Richard Winters in Band of Brothers, and Jason O’Mara and includes appearances by Rascal FlattsDwight YoakamKix BrooksLaura Bell Bundy and Sara Evans.

The 53-year-old singer has also announced that he is filming a movie this spring, saying that acting has helped make him a better artist overall.

“When you’re on a movie set, you’re surrounded by incredibly talented, creative people, and I find that environment stimulating and invigorating, and I dig it,” he says. “In order to grow in this life, you have to get outside your comfort zone, and when I’m doing that stuff, I have no idea what I’m doing, so I’m certainly outside my comfort zone.”

An exact air date for Adkins' The Night Shift episode has not yet been announced, but TheWrap.com reports that it will be sometime in early May.

Adkins kicked off his 2015 tour in Orlando, Fla., on March 3. See a list of upcoming dates here.
