Journey will have a new lead singer on its summer tour with Def Leppard while Steve Augeri recovers from a throat infection.

Jeff Scott Soto, who has performed with Journey guitarist Neal Schon, will step in for Augeri starting with a show Friday in Bristow, Va.

"Steve's been suffering with an acute throat condition since before we kicked off the tour with Def Leppard. We were hoping he'd be in well condition to handle the rigors of the road but unfortunately it appears to be a chronic condition requiring total voice rest," the band said in a statement Thursday.

Augeri's doctor will monitor his condition to determine when he may be able to rejoin the tour.
