The deal last year that kept the Arizona Coyotes in Glendale, Ariz., could face a challenge after the city's mayor called for an investigation of a meeting last June between City Council members and a team attorney.

The meeting that took place several days before the council voted to approve a $225 million agreement with the NHL franchise could have violated the state's Open Meeting Law because key information was disclosed regarding the city's negotiating plans.

On Monday, Glendale Mayor Jerry Weiers asked the state attorney general to investigate the previously undisclosed meeting. Weiers voted against the deal in June 2013 to keep the Coyotes in Glendale.

If an investigation is opened and a violation of the state's Open Meeting Law is found, the team's deal with the city could be potentially voided. If that happens, the city council would have 30 days ot ratify the Coyotes' deal in an open meeting.

"I think it's a clear violation," Weiers said, according to The Arizona Republic. "That meeting is wrong on so many levels. It's like playing poker and showing your opponents all your cards."
