The Seahawks will still face the Oakland Raiders in London this season, but on Monday it was announced they'll be playing at a different venue. Tottenham Hotspur announced that, due to "issues with the critical safety systems," construction of their new stadium has been delayed. As a result, Seattle's Week 6 game against the Raiders, as well as two of Tottenham's Premier League home games, have been moved to Wembley Stadium.

Wembley has been home to past NFL games in London, and will also host two other NFL games being played there this season, but the Seahawks and Raiders were supposed to be the first teams to play in Tottenham's new stadium, which is being built to include several NFL-specific features.

"Everyone has been so excited about the prospect of playing in the new Tottenham Hotspur Stadium and I know all at the Club are very disappointed, but determined to clear this final hurdle," Mark Waller, NFL Executive Vice-President, International, said in a statement. "We totally understand the issue. We shall continue to work with them towards making our future games at Spurs a huge success. The new stadium will be an amazing venue for the NFL and we are very excited about our long-term partnership with Tottenham Hotspur."

NFL UK announced that ticket information will be available later this week, both for those who have already purchased tickets, and also for the sale of any additional tickets at Wembley.
