Forwards Johnny Gaudreau and Sean Monahan were among four players to receive a qualifying offer from the Calgary Flames on Monday.
Forward Freddie Hamilton and defenseman Tyler Wotherspoon also received an offer before the 5 p.m. ET deadline, meaning the Flames retain the rights of all four players, who each can become a restricted free agent Friday.
Gaudreau, who will be 23 on Aug. 13, had 30 goals and 78 points in 79 games this season in the final year of his entry-level contract signed April 11, 2014. The 2014 Hobey Baker Award winner has 143 points in 160 NHL regular-season games, and nine points in 11 Stanley Cup Playoff games.
Monahan, 21, had 27 goals and an NHL career-high 63 points this season. The Flames' first-round pick (No. 6) at the 2013 NHL Draft has 159 points in 237 regular-season games in the NHL.
Forwards Josh Jooris and Joe Colborne, who each spent the entire 2015-16 season with Calgary, were among nine players who were not tendered a qualifying offer by the Flames on Monday. Each can become an unrestricted free agent Friday.
