"American Idol" Season Five favorite will play Kenickie.

There will be a changing of the "American Idol" guard in the cast of Broadway's "Grease."

According to Playbill, Taylor Hicks will exit the Broadway revival on September 7, but Ace Young will make his debut two days later.

It isn't a straight-up swap of Season Five "Idol" finalists, though. While "Idol" winner Hicks has been playing Teen Angel since June, seventh-place finisher Young will play Kenickie through Jan. 18, 2009.

This will be Young's Broadway debut, but it's hardly his first foray into acting. The Grammy nominated songwriter (for co-writing Daughtry's "It's Not Over") appeared on an episode of the sitcom "Half & Half" and on an episode of FOX's "Bones" late last season. His solo debut, a self-titled album from the Pazzo Music/Fontana label, is now available.

"Grease" is now playing at the Brooks Atkinson Theatre.
