Florida Panthers forward Curtis Valk will become the fourth player to make his NHL debut for the team this season, taking the ice Tuesday night against the Dallas Stars. Valk, 24, is slated to center the fourth line between Micheal Haley and Connor Brickley. He will be filling in for injured captain Derek MacKenzie, who suffered a lower-body injury Saturday in New Jersey. Panthers coach Bob Boughner said the team would evaluate MacKenzie again on Tuesday afternoon before deciding if he makes the three-game road trip to California this weekend. The 5-foot-9, 170-pound Valk signed an entry-level contract over the summer with the Panthers and began the season with AHL affiliate Springfield. In 16 games, he has six goals and nine assists with the Thunderbirds. “Small guy, but he competes hard,” Boughner said. “He’s had some success down there in the American League according to [Springfield coach Geordie Kinnear]. He’s a real reliable player. He’s getting rewarded for his play in the American League and he fits exactly what we need tonight.”
