One of the main reasons NFL teams cant allow their home games to be played in London is because of their stadium lease, the new deal for the Bengals changes that possibility for them.
Some leases throughout the league require all 'home' games to be played in the home stadium, the previous lease for the Bengals in regards to Paul Brown Stadium stipulated that, in their new deal it doesn't.
The Bengals have announced a new agreement with Hamilton County which will allow the team to "participate in the NFL’s International Series games.”
Paul Brown Stadium will undergo many changes such as wireless internet service, a high-definition scoreboard, a new weight room and an expanded locker room. The team will trump up $6 million towards all the developments.
Bengals president Mike Brown spoke of the undertakings with the teams stadium: "We wanted to demonstrate our interest in working together to ensure that The Banks is a viable location for this project, We all know that the Cincinnati area is a great place to live and work. Landing this project will let the nation know it as well.”
The new deal has definitely opened up the opportunity for the Bengals to participate in a home game at Wembley Stadium, something I'm sure British fans of the game will be very glad to hear.
