Forwards Michael Cammalleri, Lee Stempniak and Matt Stajan, and defenseman Kris Russell are among Calgary's pending unrestricted free agents, all of whom could moved by the deadline.
The Los Angeles Kings, Phoenix Coyotes, Detroit Red Wings, New York Rangers, Montreal Canadiens and Pittsburgh Penguins are among the teams looking for a top-six winger and could target the likes of Cammalleri and Stempniak.
Cammalleri and Stempniak have limited no-trade clauses and could have a say in where they end up.
Cammalleri can list up to seven teams he will not accept a move to.
Flames forward Curtis Glencross is also being targeted by several teams, but he owns a no-movement clause and has one-year left on his contract beyond this season.
It's unclear if the Flames are willing to move Glencross, or if he would accept a deal out of town, but the asking price is believed to be higher than that of Cammalleri or Stempniak, due to his contractual status.
