Saturday's Carrie Underwood concert in Kansas City has been rescheduled for May 1st, after she lost her voice following Wednesday's concert in Chicago.

Carrie spent part of Thursday watching Star Trek Next Generation in an effort to give her pipes a rest. She tweeted, "Been in bed all day … finally feeling a bit better. I'm currently watching Star Trek Next Gen. I love it when they fight the Borg."

As a result of the Kansas City date change, Carrie's gig in Springfield, Illinois will be moved to May 6th. Tickets will be honored for each new date. The Blown Away tour resumes Tuesday in Memphis.
