Tkachuk is second on the Flames with 24 goals and third with 49 points; Brodie has 32 points (four goals, 28 assists) in 73 games, and is second to defenseman Mark Giordano in average time on ice with 23:40.
Calgary remains without forward Johnny Gaudreau, who leads the Flames with 82 points (23 goals, 59 assists). He is away from the team after returning home to New Jersey to be with his father, Guy Gaudreau, who had a cardiac event March 25.
"We're in contact with him every day, twice a day," Gulutzan said. "As far as everything there, I think it's on the real upswing, which is real positive for us and his family. We're continuing to make sure we're wishing them the best there.
"It's really family first there right now. If things get real good, we'll try to get Johnny back, but he needs to be there right now."
The Flames earlier shut down forwards Sean Monahan and Kris Versteeg for the season.
Monahan, who leads Calgary with 31 goals and is second with 64 points, will have wrist surgery. Versteeg hasn't played since March 18, his second game back after missing 49 because of hip surgery. He had eight points (three goals, five assists) in 24 games.
