Tim McGraw may be ready for football, but is he ready for tennis? Maybe not, but the superstar, along with rock band Daughtry will be making a musical "racket" for a tennis-related charity later this month. They're among the acts scheduled to perform at tennis champ Andre Agassi's 14th annual Grand Slam for Children concert, Sept. 26 at the Wynn Las Vegas luxury casino resort.

Other guests appearing the the benefit include comedian Dane Cook and R&B singer Brian McKnight. Famed producer/composer David Foster will serve as musical director. The event has raised nearly $75 million since 1995, in support of the Andre Agassi Foundation and the Andre Agassi College Preparatory Academy in Las Vegas.

"We have 300 million people in this country," the retired tennis legend said recently. "We got to get the racket in more kids' hands. We have to create a grass-roots level that connects."
