Dierks Bentley is returning to the road just three days after undergoing outpatient surgery to repair a torn ligament in his knee. He sustained the injury March 20 during a Kenny Chesney concert in Biloxi, Miss. Bentley fell when he jumped from a 5-foot tall riser to join Chesney and Keith Urban onstage at the end of the show. He underwent surgery Monday (March 29) in Nashville. Bentley will open Chesney’s Thursday night (April 1) concert in Grand Rapids, Mich.
