Toronto Maple Leafs fans hoping to travel to attend second-round series games against the Florida Panthers may be denied tickets.

The Panthers have limited ticket sales for Game 3 and Game 4 of the series to US residents.

No explanation was immediately given, but it is known that many Maple Leafs fans travel to attend games of their favorites, especially in American states where it is warm during the winter.

Underneath “Important Event Information” on the Ticketmaster site page associated with a link to the Panthers site, a note explains the terms of sale.

“FLA Live Arena is located in Sunrise, Florida. Sales for this event will be limited to residents of the United States. Residency is determined by the billing address associated with the credit card. Orders made by residents outside of the United States will be canceled without notice and refund.

The Panthers and the NHL did not immediately respond to requests for comment on the situation. Dates for the games in Florida have yet to be released. Game 6 of the series will also take place at the FLA Live Arena, if necessary.

Game 1 of the series will be played Tuesday at Scotiabank Arena. Game 2 is Thursday in Toronto, then the series continues in Florida.

The Edmonton Oilers are the only other Canadian team still in the NHL playoffs. They begin their second-round series against the Golden Knights on Wednesday in Las Vegas.

There did not appear to be any restrictions in place for Canadian residents to purchase tickets for matches played at T-Mobile Arena.
