A source has informed CSN-California.com that the Sharks have approached Clowe's agent about the possibility of waiving his no-trade clause, and that a deal could happen as soon as Sunday.
The most likely suitors appear to be Boston, Montreal and the New York Rangers, according to CSN-California. Sharks director of pro scouting John Ferguson Jr. was in Philadelphia for the Bruins-Flyers game on Saturday afternoon. He flew to Montreal for the Canadiens-Rangers game later that day, according to Renaud Lavoie of RDS.
Ferguson also attended the Bruins' home game with Montreal on Wednesday.
It's been a disappointing season for Clowe, a 6-foot-2, 225-pound power forward. He entered Saturday with no goals and 11 assists, along with a team-high 77 penalty minutes, in 27 games. Clowe's 62 shots are the most by any player who hasn't scored a goal this season.
Clowe is in the final season of a four-year, $14.5 million contract, and is due to become an unrestricted free agent in July.
The Bruins could be interested in Clowe after seeing Jarome Iginla dealt to Pittsburgh earlier this week.
