Trocheck, who did not play in Carolina's 3-2 overtime win in Game 3 at Tampa Bay on Thursday, sustained a lower-body injury when the center collided with forward Warren Foegele late in the second period of a 2-1 loss in Game 2 on Tuesday. Trocheck returned for the third period but played one 16-second shift before leaving.
Hurricanes coach Rod Brind'Amour had said that Trocheck and Foegele, who sustained an upper-body injury after he was hit by Lightning defenseman Erik Cernak with 2:20 remaining in the second period of Game 3, each was a game-time decision Saturday. Foegele was able to play in Game 4.
Carolina trails 2-1 in the best-of-7 series.
Trocheck scored 43 points (17 goals, 26 assists) in 47 regular-season games, second on the Hurricanes to forward Sebastian Aho (57 points; 24 goals, 33 assists). He has scored three points (two goals, one assist) in eight playoff games.
Carolina forward forward Nino Niederreiter missed his fourth straight game with an upper-body injury sustained during practice May 29. Niederreiter scored 34 points (20 goals, 14 assists) in 56 regular-season games and one goal in six playoff games.
Forward Morgan Geekie replaced Trocheck in the lineup for the second straight game. Geekie had three shots on goal in 8:51 in Game 3.
"I think as a group, we always just want to play the same way," Hurricanes captain Jordan Staal said. "The guys who have come in have played really well and have just been preparing as pros to step in and play well.
"Geekie had a great game, he had a bunch of chances and we're going to have other guys come in and out. Playoffs, it's an unfortunate part of it: You won't get through a whole playoff run without injuries. It's the depth our group has that hopefully gets us over the edge and gets us through these few injuries."
