Fever's McCall performs with Carrie Underwood

NEW YORK (AP) Erica McCall is still in a state of shock. She can't believe that she got to perform on stage with Carrie Underwood at a concert.

The Indiana Fever center sang the guest verse of "The Champion" at the country music star's show Sunday at Bankers Life Fieldhouse.

"It's up there, definitely an experience I will never forget," McCall said in a phone interview with The Associated Press on Tuesday. "It's up there with going to the Final Four with (Stanford). I'm itching to get back on stage."
