Here is the comment from John Breech CBS Sportsline
This London game actually comes with a twist because we're getting our first ever PRIME TIME GAME in London. As you've probably noticed, most games in England kickoff at 9:30 a.m. ET, however, since that would be an ungodly hour for Rams and Cardinals fans in Arizona and California, this game will kick off at 1 p.m. ET, which means a 6 p.m. local start in London. That should give Peterson enough time to take his entire team on a tour of Big Ben and Buckingham Palace.
