The Denver Broncos are looking forward to a new era after the team's record-breaking sale to the Walton-Penner family ownership group was confirmed.

The deal, worth $4.65billion, a record for any American sports franchise, was unanimously approved by NFL owners on Tuesday.

And the group, fronted by Walmart heir Rob Walton, could not wait to get started.

"We are just so excited to become officially a part of the Broncos," Walton said. "It's a big, big day for us. Really, really exciting.

"It's been a great process and I want to extend a thanks with all the owners we've been involved with. Their warm greeting and support as we've met them along the way – haven't met all of them yet, but we're getting close – has just been good.

"It's a very wonderful group to become associated with.

"We want to acknowledge [former owner] Pat Bowlen's outstanding legacy, also, as well as the family. Pat's leadership and commitment to build a successful team and business, and we'll continue to build on that.

"Putting a winning team on the field is our number one priority. We can't wait to get to Denver, join our new colleagues and get to work."

NFL commissioner Roger Goodell added: "This is a group that is going to be great for the Denver community.

"Their commitment to winning, but more importantly their commitment to making sure the Broncos franchise is an important part of the Denver community. We're thrilled about that."
