Earlier this month, NFL UK managing director Alistair Kirkwood said two teams had "agreed conceptually" to play home games in Britain in addition to the regular season game between the Denver Broncos and San Francisco 49ers at Wembley in October.
"Playing one game in the UK is a significant investment. Playing a second game is an even bigger investment," the league said in a statement on its website yesterday. "As we considered this, the uncertainty related to the ongoing CBA discussions linked to the current global economic climate were critical factors in our decision not to play a second game in the UK.
"Our ambition to bring a second game to the UK is as strong as ever. Once the current uncertainty is resolved, we will be in a strong position to bring multiple games to our UK fanbase."
League bosses in the US had hinted there could be as many as four games per season played in Britain by 2012.
