But according to one official involved with this weekend's upcoming game between the Patriots and Buccaneers, the grass is no longer an issue.
“We’ve handled it,” Alistair Kirkwood, the managing director for NFL United Kingdom, told the Boston Herald's Ian Rapoport.
Kirkwood noted that the 2007 game followed the second-wettest day of the year, and the turf was new.
“We’ve come up with lots of different ideas as far as how can it get better,” Kirkwood told the Herald. “The field will be fine.”
Tom Brady, in his conference call with London reporters on Tuesday, seemed more excited than worried about playing on the field.
"To play in Wembley Stadium, as historic a stadium as in the entire world, I think our team is all very excited for that," Brady said.
"I’ve heard great things about this stadium," he later added. "It’s an incredible stadium. I’ve seen it on TV and I’ve watched a lot of European soccer also, so I’m very familiar with the grounds we’re playing on and I’m hoping to go in there and get a victory this weekend."
