Tim McGraw and Luke Bryan are among the celebrities announced to participate in the Tug McGraw Foundation's inaugural celebrity sporting clay shootout schedule for June 5 in Nashville. The event at the Nashville Gun Club will benefit the foundation and its efforts to improve the lives of military service members who have been affected by post-traumatic stress disorder and traumatic brain injury. The shooting competition will feature 15 teams, including pros and celebrities. Others scheduled to participate include Craig Campbell, Josh Gracin, JT Hodges, along with Eddie Montgomery and Troy Gentry of Montgomery Gentry and Brad and Brett Warren of the Warren Brothers. Tug McGraw, the singer's father, established the foundation in 2003 to raise funds to enhance the quality of life of children and adults with brain tumors. The organization widened its scope to support advances in medical care and quality of life for the nation's battle-wounded, ill and injured service members. Tug McGraw died in 2004.
