ESPN sideline reporter Erin Andrews arranged for more than 30 participants in the Taco Bell All-Star Legends & Celebrity Softball Game to sign her game jersey, and the autographed memorabilia is now being auctioned to benefit the family of Shannon Stone, the Rangers fan who fell to his death at a Texas game just days before the All-Star Break.

Among the celebrities and baseball players who signed the jersey were Andrews, Nick Jonas, Jordin Sparks, Rickey Henderson, Joe Torre, Kate Upton, Chris Pratt, Greg Grunberg, Rollie Fingers, Chord Overstreet, James Denton and Larry Fitzgerald. The signatures were witnessed by MLB authenticators.

Bidding on the item runs through August 7 at 6 p.m. EDT. The opening bid was $500.
