The deal is worth $660,000 at the NHL level or $65,000 at the AHL level.
The 23-year-old restricted free agent played for the Milwaukee Admirals in the American Hockey League last season. He was second in the league in wins (31) and shutouts (five) and posted a 2.17 goals-against average.
He was selected by Nashville in the second round (No. 54) of the 2007 NHL Draft.
