A few ears perked up Friday morning when — in answer to a question about star forward Daniel Sedin's progress or lack of same — Vancouver Canucks coach Alain Vigneault admitted he has never read the National Hockey League's concussion protocol.

Then again, neither had I.

So I called the league, got a copy of the document sent to me, and the mystery was instantly cleared up. The NHL protocol for diagnosing concussions, treating them and eventually releasing concussed players back into the wild is, while doubtless well-intentioned, a little like an impenetrable poem or the lyrics to I Am The Walrus — it might be saying this, or it might be saying that.

The Canucks, it appears, have been playing it straight with Daniel. Judging by the collapse of the power play in his absence, it could be the hardest test of integrity they've ever had to pass. Maybe even a season-ending one.

Henrik Sedin's fruitless search for his missing brother through two lost games of this first-round series against the Los Angeles Kings has been like an amputee "feeling" his phantom limb. Without Daniel, the power play — oh-fer in goals scored, and with two (count 'em, two) short-handers surrendered Friday — was being booed by the second period of a second consecutive 4-2 loss.

Surely the temptation to rush Daniel back, ready or not, is nearly overwhelming.
