Whoops: After Avalanche break signing, Matt Carkner actually signs with Islanders

At 1 p.m. ET Sunday, the Twitter feed of the Colorado Avalanche sent out this tweet alerting the world of two new additions to the squad. A half hour after that tweet, Bob McKenzie of TSN spoke with Matt Carkner's agent and was told that nothing was official yet with the Avalanche.

A little over an hour after Colorado's initial tweet, TSN's Aaron Ward confirmed that Carkner had actually signed a three-year deal with the New York Islanders. The Ottawa Sun's Bruce Garrioch reports it's $1.5 million a season and the Senators offered just a one-year, $750,000 contract.

Carkner told NHL.com's Brian Compton that confusion along the way was the likely explanation for the mishap:

"It was pretty early on in the day and I don't know if they were trying to exchange information for my address to make an official offer, and somewhere along the line someone must have confused Colorado, saying that maybe I accepted the deal," Carkner told NHL.com. "I never told anyone that, but things like this happen. We called Colorado and apologized right away. We didn't mean to mislead them at all. It ended up a couple of hours later, I agreed to terms with the Islanders."

Carkner will bring toughness and his fighting skills to the Islanders blue line, and now he and Brian Boyle of the New York Rangers will get a chance to be reacquainted six times a year beginning next season.

Having already chirped the Minnesota Wild Twitter account after their announcement that they've submitted offers to Zach Parise and Ryan Suter, no word on this fail from the Los Angeles Kings Twitter yet.
