The Calgary Flames and forward Mathias Emilio Pettersen have agreed to a three-year, entry-level contract, the team announced Monday.
Pettersen, 20, a Norway native, was a sixth-round pick of the Flames in 2018.
He spent the last two seasons at the University of Denver and had a team-high 35 points (13 goals, 22 assists) for the Pioneers in 2019-20.
The 5-foot-10, 175-pound left-handed center leaves Denver with 19 goals and 65 points in 76 games on his resume. In his tenure, the Pioneers finished 21-9-6 this season before the NCAA tournament was canceled, and last season Denver advanced to the Frozen Four before falling to UMass, 4-3, in overtime in the national semifinal.
