Tuesday is the NHL's hard-and-fast deadline for the city of Glendale to agree on an arena deal, or the Coyotes could move.
And, it's possible the Phoenix hockey team could come to Seattle.
At a special city council meeting in Glendale Tuesday night, the council was expected to vote on a financing deal, which includes an out clause for the city after five years if the team loses to much money.
However, the league has a back-up plan in case city officials and potential ownership in Glendale can't come to an agreement.
KeyArena has already set aside NHL dates for this fall. The NHL met with Seattle officials a few weeks ago.
"They made it clear if they were able to secure the Coyotes, they would play at KeyArena without any commitment by the city a new arena would be built." said Seattle City Council Member Tim Burgess.
KeyArena would seat about 11,000 fans for hockey games and still has functional ice making equipment.
What about the agreement to build a new arena in Seattle for hockey and basketball?
"An NBA team first, then a hockey team if one comes," said Burgess.
The NHL currently owns the Phoenix Coyotes. They purchased the team in 2009 and hoped to sell ownership rights within a few months.
The league has agreed to sell the team to Renaissance Sports and Entertainment for $170 million pending an arena deal, according to SB Nation. The NHL also has an agreement to sell the Coyotes to an ownership group in Seattle for $220 million if an agreement isn't reached in Glendale.
