Brian Burke has been burning up the phone lines to add a defenceman.

And if the Maple Leafs general manager has his way, he will do so by the time the Leafs play host to the New York Islanders on Tuesday.

“We have a couple of things going, and I don’t know if anything is going to come of it or not, but I spent a good chunk of time this morning,” Burke told reporters at the MasterCard Centre on Monday afternoon. “We’re trying to add by tomorrow if we can, trying to put a player in the lineup to help us soon as possible. Our priority is to add a defenceman.”

Any hints on specific players?

“I can tell you, but I would have to kill you,” Burke said. “It’s tampering. I am not trying to be a smart ass.”

Burke this week also will work hard to sign forward Clarke MacArthur to a contract extension. If that does not happen by the NHL trade deadline on Feb. 28, MacArthur could be traded.

“We have not quantified it yet,” Burke said after taking part in a question-and-answer session in front of approximately 300 fans. “I know he would like to stay, and I think he would be crazy not to. We have not put an amount on it yet. That will happen this week.”

One player who will not be traded for anyone is defenceman Luke Schenn.
