Predators defenseman Mark Eaton and center Yanic Perreault were placed on the injured reserve roster Friday and are each expected to miss two to four weeks with strained knee injuries.
Eaton, who was injured during a second-period collision with Blackhawks forward Mark Bell Wednesday night in Chicago, left that game and missed Thursday night's home match against Vancouver.
Perreault was injured in Thursday night's game against Vancouver during a late Predators power play. Earlier in the game, Perreault had scored a power-play goal to tie the score at 1-1. Nashville went on to win by a 3-1 margin.
There were no plans to recall any players from the Predators' top minor-league affiliate in Milwaukee Friday.
