Tim McGraw will headline an April 10 concert in Austin, Texas, to benefit the non-profit Gridiron Heroes Spinal Cord Injury Organization. The concert at Auditorium Shores will also feature actor-musician Billy Bob Thornton and several special guests. McGraw and Thornton are currently shooting the film Friday Night Lights in Texas. The concert is being organized by director Peter Berg, who was filming a football game in San Antonio last fall when a player was paralyzed after suffering a spinal cord injury while making a tackle. McGraw, Thornton and Berg announced the concert during a Tuesday (March 2) press conference in Austin.
