The NHL reportedly is investigating possible tampering by Toronto Maple Leafs head coach Ron Wilson.

The league is looking into Wilson's comments made last Tuesday during a radio interview about Toronto's interest in forwards Daniel and Henrik Sedin, both of whom re-signed with the Vancouver Canucks less than 24 hours later.

"You're hearing right now — and this sounds very contradictory — but there is a real possibility I would think that we would be going after the Sedins. Let's just speculate there," Wilson said on the Fan 590 in Toronto.

NHL deputy commissioner Bill Daly wouldn't confirm an investigation had been launched, but admitted the Canucks, who signed the twins to identical five-year, $30.5-million US contracts, hadn't filed a formal complaint with the NHL.

"The league has indicated that they are looking into it, so we will have no public commentary at this time," Maple Leafs general manager Brian Burke told the Globe and Mail on Thursday.
