The prognosis: immediate surgery, Saturday night in Vancouver.

Toronto Maple Leafs centre Dave Bolland was rolled out of Rogers Arena on a stretcher after Saturday's 4-0 loss to the Vancouver Canucks, just after coach Randy Carlyle told reporters about the planned surgery.

Carlyle, who had just been briefed by medical staff, said the cut was similar to the gruesome Achilles injury suffered by Erik Karlsson last year, but added that he didn't have a sense of the severity.

The surgery is telling enough.

"I don't know of the degree of severity or which tendon but he did suffer a cut into that area, so he will have surgery to repair that tonight," said Carlyle.

This is bad news for the Toronto Maple Leafs, which is searing obvious. The team is now without its top two centres, as Tyler Bozak is out at least another dozen or so days as he is on long-term injured reserve.

When asked about how the Leafs fill the void, Carlyle smiled and chuckled, "Do I really have to respond to that?"

In general, he called the Leafs effort versus the Canucks the team's worst of the year. "Terrible game for us."

Bolland was hurt in the second period of the game on Saturday, during a collision on the boards with Vancouver's Zack Kassian. Kassian's skate stepped on the back of Bolland's left leg. He could not place any weight on the leg as he hobbled off the ice on the shoulders of two teammates.
