Barry Trotz has a choice to make.

The Nashville Predators coach said Wednesday that veteran left wing Steve Sullivan will miss Game 4 of his team's Western Conference semifinal series with the Vancouver Canucks (7:30 p.m., Bridgestone Arena) because of a lower body injury sustained in Tuesday's 3-2 overtime defeat.

Thus, Trotz must decide whether to play J-P Dumont or Colin Wilson. Or both.

"I have two forwards left and one will definitely be in because [Sullivan] is not in," Trotz said. "And I have to look at the rest of our lineup."

Dumont played the final two games of the Anaheim series when Martin Erat was injured. He had an assist in the series-clinching victory and was on the ice as the extra attacker when Shea Weber scored in the final minute of regulation and forced overtime in Game 5.

"Against Anaheim, when [I] got the call, I think [I] was ready to go," Dumont said. "You never want to see one of your teammates go down, but at the same time I want to play. Hopefully I'm going to be in."

Wilson, one of four Predators who played all 82 games of the regular season, has not appeared in a playoff game this year. Trotz said he considered Wilson for his Tuesday lineup but ultimately decided to stick with the same group he used in the first two games against Vancouver.

"[Wilson] is ready," Trotz said. "… I feel he's ready for the series now. … His play at the end of the year wasn't where I expected it to be. He didn't start the first series and no one allowed him to get into the first series because everyone played pretty well.
