This time, when the Patriots play St. Louis in London, Gregory is hoping to be on the winning end.
"It's definitely a cool experience," the Patriots safety said of playing at Wembley. "Obviously it's a long flight and things like that. But it's no longer than it is going out to the West Coast."
In 2008, Gregory and the Chargers played in Buffalo the week before the London game. The Chargers traveled directly from Buffalo to London.
This week, the Patriots will travel late Thursday/early Friday. They are planning to use Friday as a rest day to acclimate to London.
"We'll get out there in plenty of time to adjust to the time and all that stuff," Gregory said. "It will be a good experience for the guys that haven’t been."
Gregory has played in only four games this season because of a hip injury. Gregory does not know whether he will make the London trip.
