Bill Belichick has said that the New England Patriots had a "good work week" in Philadelphia.
The AFC East champions practiced with the Philadelphia Eagles earlier this week, before beating Chip Kelly's side in a pre-season game on Friday.
After returning to Foxboro, the head coach told reporters: "I think the overall week against Philadelphia was a good work week. We had good, competitive practices without any real problems so that was very productive for us.
"We had a chance to go out there and play football with all the situations, substitutions, the whole game operations, for the first time in quite awhile and that was good for us as a football team, also had to go on the road, deal with all the logistics that go along with that.
"I feel like we made a lot of progress. Of course there are a lot of things we need to work on, we need to continue to stress and get better at. We need to see and be exposed to different things and we'll certainly get that this week."
The Patriots play the Tampa Bay Buccaneers next week.
