Suniev was a third-round pick of the Flames in the 2023 NHL Entry Draft, who made his NHL debut last season, playing one game. The 21-year-old forward has 23 points (15G / 8A) in 55 games this season with the Calgary Wrangelrs (AHL).
Yan Kuznetsov will draw into the lineup for the first time in three weeks, sending Brzustewicz to the sidelines on Thursday as a healthy scratch. The 21-year-old Brzustewicz is averaging 15:25 time-on-ice and has five points (1G / 4A) in 27 games this season.
With Connor Zary (upper-body) returning from a multi-week injury, Othmann will be the odd man out of the lineup as a healthy scratch. The 23-year-old Othmann scored a goal in Monday's 9-2 loss to the Colorado Avalanche, his first goal as a member of the Flames.
John Beecher will be a healthy scratch on Thursday, allowing Pospisil to re-enter the lineup from a one-game absence. The 26-year-old Pospisil played 81 games in the 2024-25 season, but has been in and out of the lineup since making his 2025-26 debut in late January. The Slovak forward has two points (1G / 1A) and 37 hits in 12 games this season.
Hunter Brzustewicz will be a healthy scratch on Thursday, allowing Kuznetsov to re-enter the lineup. The 24-year-old Kuznetsov has 12 points (4G / 8A) in 52 games this season, but has not played in nearly three weeks.
Zary has not played since suffering an upper-body injury on March 20th, but he will make his return on Thursday against the Vegas Golden Knights. The 24-year-old Zary is averaging 14:31 time-on-ice and has 24 points (11G / 13A) in 67 games this season
Wolf only lasted half of a period before being relieved by Devin Cooley on Monday, allowing four goals on 16 shots (.750 SV%) in an eventual 9-2 loss to the Colorado Avalanche. The 24-year-old Wolf was on a solid stretch before his recent blip, posting a 2.13 GAA and .920 SV% in five games (3-2-0). The Flames enter Thursday's contest as significant +210 road underdogs against a Vegas Golden Knights team that has scored three or more goals in three straight games (1-0-2).
Hurtig was a seventh-round pick of the Calgary Flames in the 2023 NHL Entry Draft that has just been rewarded with a three-year, entry-level contract. The 20-year-old defenseman scored 19 points (6G / 13A) this season in 64 games with the Calgary Hitmen (WHL).
The 70th overall pick in the 2023 NHL Entry Draft, Castagna was acquired from the Mammoth earlier this season in the Mackenzie Weegar trade. Castagna recently finished his Junior season of NCAA hockey at Cornell University, where he tallied 15 goals and 19 assists in 34 games.
John Beecher will draw back into Calgary's lineup on Monday, resulting in Gross being a healthy scratch. The 23-year-old Gross made his NHL debut last week and remains in search of his first point through two games.
The Flames have alternated goalies semi-evenly in recent weeks and will turn to Wolf for a second consecutive game on Monday against the Colorado Avalanche. The 24-year-old Wolf was serviceable in Saturday's 7-3 win over the Vancouver Canucks, saving 31 of 34 shots (.912 SV%). He has a solid 2.13 GAA and .920 SV% in his last five appearances (3-1-0). That said, the Flames enter Monday's contest as massive +308 road underdogs against an Avalanche team whose five-game point streak (4-0-1) was snapped on Saturday in a 4-2 loss to the Winnipeg Jets.
Zary has not played since suffering an upper-body injury on March 20th and it is still unclear when he will return, though his status remains day-to-day. The 24-year-old Zary is averaging 14:31 time-on-ice and has 24 points (11G / 13A) in 67 games this season.
Honzek has not played since undergoing surgery in mid-November to address an upper-body injury and has been sidelined since. The 21-year-old Slovak forward also was unable to represent his country at the Olympics as a result. He had four points (2G / 2A) in 18 games this season.
