Carrie Underwood set to perform for first time since accident

The singer - who's kept a low profile since suffering a serious facial injury late last year - will take the stage Sunday at the Academy of Country Music Awards in what will be her first performance since the accident. She initially revealed through her rep that she'd sustained a broken wrist, but expounded in a blog post two months later that the accident left her in need of "between 40 and 50 stitches" to her face.
