Martin Erat had been battered and beaten this series. The Ducks turned several of his front teeth into Chiclets in Game 2, but the forward came back and played. In Game 4, the Ducks may have given Erat one punch too many. At around the 16-minute mark of the second period, Anaheim's Jarkko Ruutu came across the ice and hit Erat high with his shoulder. Erat immediately fell and appeared dazed by the time a Predators trainer came to his aid. Ruutu was given an interference penalty. Erat skated off slowly but did not return with what was deemed an upper-body injury. After the game, Coach Barry Trotz couldn't give an update on Erat, who tied for the team lead in points this season. "He has been there all year playing hard for us," defenseman Ryan Suter said. "He's one of our top players. It was an unfortunate hit — I don't know what I can say, but it was unfortunate and it's too bad he was unable to come back." Forward Steve Sullivan slid into Erat's place and had his highest ice-time total of this postseason (12:37). Sullivan notched an assist on Joel Ward's power-play goal in the second period.
