Benn is third on the Stars with 41 points (21 goals, 20 assists) in 60 games, behind Alexander Radulov with 47 points (16 goals, 31 assists) and Tyler Seguin with 57 points (26 goals, 31 assists). Montgomery was uncertain if Benn will be able to play Tuesday.
"It happened last night; he was trying to play with it, thought he could get through the game," Montgomery said. "One jarring hit, upper body, back spasms, I don't know what it is. But he's staying on the trip."
Dallas (31-26-5) holds the first wild card spot for the Stanley Cup Playoffs for the Western Conference, which makes it more deflating to lose Zuccarello, who was acquired from the Rangers for a conditional second-round pick in the 2019 NHL Draft and a conditional third-round pick in 2020.
Zuccarello, who had 37 points (11 goals, 26 assists) in 46 games with the Rangers, was noticeable from the start against the Blackhawks. He was quick, he was aggressive, and he adjusted quickly to new linemates. Zuccarello started on the top line with Benn and Roope Hintz, but he played with Seguin and Radulov after Benn could not continue.
Seguin said playing with Zuccarello was "awesome."
"I mean, unfortunately it was only two periods," said Seguin, who had the primary assist on Zuccarello's goal, which gave the Stars a 3-0 lead at 18:16 of the second period. "But his playmaking, his vision, you saw it from the first shift on and it was fun to play with him."
Montgomery focused on an early pass from Zuccarello to Esa Lindell, which almost resulted in a goal for the Stars defenseman, as something that immediately got his players excited.
