When Trace Adkins fell off the wagon while headlining the Country Cruising musical cruise earlier this month, after more than 12 years of being sober, he immediately realized the danger he was in, left the ship and checked into rehab.

But while the singer's first thoughts were on getting his own health under control, he had another show that he was also supposed to headline on Feb. 8. And now, thanks to Brantley Gilbert, ticket holders will still get their money's worth.

Gilbert has stepped in to fill Adkins shoes at the upcoming Great American Outdoor Show in Harrisburg, Penn. The show, presented by the National Rifle Association, is part of a nine-day event that includes activities centered around hunting, fishing and other outdoor hobbies.

Gilbert is set to headline his own Let It Ride Tour, which includes Thomas Rhett and Eric Paslay as his opening acts. The tour's official start date is Feb. 15 in Indianapolis, Ind. See all of his upcoming shows here.

Meanwhile, Adkins left the rehab facility over the weekend to purchase a guitar at Chafin Musicenter in Lake Worth, Fla. The 52-year-old was reportedly accompanied by rehab employees for the outing.

There is no word yet on how long Adkins will stay in rehab.

“Trace has entered a treatment facility after a setback in his battle with alcoholism,” his rep said following the incident. “As he faces these issues head-on, we ask that his family’s privacy will be respected.”

No other statements have been made regarding his recovery. His next scheduled concert is Feb. 18 at the San Antonio Stock Show & Rodeo, but it remains unclear if he will be able to perform. Keep track of updates here.

Gilbert is also slated to headline at the Tropical Nights Boots in the Sand getaway, which runs from Feb. 23-27 at the Riviera Maya in Mexico. Billy CurringtonDierks Bentley and Jana Kramer will also headline separate nights of the luxury country music getaway.
