Lomberg had 29 points (12G / 17A) in 58 games with Stockton (AHL) last season and had a brief four-game showing with the Flames, where he had 17 PIMS. Lomberg is a fourth-line player who could have a spot in Calgary next year after Garnet Hathaway signed with the Capitals this summer.
Nichushkin has been a huge disappointment for the Stars since selecting him No.10 overall in 2013. Nichushkin failed to live up to expectations early in his career before going to the KHL for two years (2017 and 2018). He returned to the NHL last year but did not score a goal while collecting just 10 assists in 57 games. Nichushkin has one-year left on his deal that carries a $2.95M cap-hit (per PuckPedia).
Merzlikins, 25, was selected by the Blue Jackets in the third-round back in 2014 but remained with Lugano in Switzerland, where he had a 2.44 GAA and .921 SV% in 43 games this season. Merzlikins represented Latvia at the World Championship, where he had a 2.78 GAA and .914 SV% in five games.
Olivier is an undrafted centre who played five years in the QMJHL, where he had 27 goals and 22 assists (49 points) with Sherbrooke in his final season. Olivier turned pro this year, collecting four goals and eight assists (12 points) in 54 games with Milwaukee (AHL).
The Flames have clinched a roster spot and it looks like Monahan will be the latest forward to be rested. Mikael Backlund is expected to replace him in the lineup and Derek Ryan will skate on the first line.
Heinen played through an illness on Sunday but will be replaced by Chris Wagner on Tuesday.
