The Nashville Predators summoned goaltender Marek Mazanec from the AHL on Saturday night, leading to speculation about the health of starter Pekka Rinne.
Rinne appeared to be in discomfort after allowing San Jose Sharks winger Joel Ward to score the go-ahead goal with about eight minutes remaining in Game 1 of their second-round playoff series.
He was replaced by backup netminder Carter Hutton with 20 seconds left.
Mazanec went 19-15-5 with a 2.45 GAA, a .912 save percentage and four shutouts with the AHL's Milwaukee Admirals this season.
Game 2 between the Predators and Sharks goes Sunday night at the SAP Center in San Jose.
