According to TSN's Bob McKenzie, Knight then reached agreement with the Flames on a two-year entry-level contract.
Knight, a 2009 fifth-round (No. 135) selection by the Panthers, just completed his fourth season at the University of North Dakota where he was a top 10 finalist for the Hobey Baker Award as the nation's top collegiate hockey player.
"Corban Knight is a player our scouts have been watching closely throughout his collegiate career," Flames general manager Jay Feaster said in a statement released by the team.
He led the Fighting Sioux in assists (33) and was second in goals (16) and points (49) and third in penalty minutes (40). He finished his college career with 52 goals and 94 assists for 146 points along with 145 penalty minutes in 161 games.
"When Florida did not sign Corban this spring, we contacted them and asked for permission to speak with him," Feaster said. "During the past 10 days we spoke with Corban and his agent, and were pleased to learn Corban wanted to start his pro career in Calgary. We were able to consummate the trade today with Florida, and are confident we will get Corban signed when permitted in July. We are thrilled to add him to our organization, and look forward to his debut in a Flames sweater this fall."
