A marijuana company has come forward as the unlikely wannabe name sponsor for an NFL team’s stadium.

Native Roots – one of Colorado’s biggest weed dispensaries – said it wanted to buy the naming rights for the Denver Broncos’ Stadium – after the current name sponsor filed for bankruptcy, raising questions over the deal, reports CBS Denver.

Colorado made it legal for over-21s to possess small amounts of marijuana in 2014.

Native Roots may have chosen an unusual date to break the unexpected news – April Fool’s Day – but the owners aren’t joking. They want to change the name Sports Authority Field at Mile High to Native Roots Field at Mile High.

“It’s not a joke, we’re very serious,” founding partner Rhett Jordan told the local TV news channel.

If Native Roots did take over it would use its symbol of a simple tree with roots in front of a huge marijuana leaf over the entrance, CBS reports.

“We’ve always been huge fans of the Broncos, we felt like this was a great opportunity to bring two brilliant brands together,” Jordan added.

Sports Authority is an American sporting goods chain that recently filed for bankruptcy, sparking speculation whether it would have to forego its $6 million (about £4.2 million) a year name sponsor contract.

Native Roots told CBS4 it is ready to make a multi-million commitment should Sports Authority be forced to withdraw.

But in a statement the Broncos said: “Sports Authority has been a great partner for many years and we certainly hope to keep it that way.”
