Thad Lewis has said that the Buffalo Bills must build on their performance from last week's narrow win over the Miami Dolphins.

The AFC East side ended a two-game losing streak when Dan Carpenter kicked a late field goal to give the Bills a 23-21 victory.

The quarterback told reporters: "Every week is critical but it's a division win, so it was important that we got that first division win because all the calls are not played yet.

"To compete in this division, you have to win in this division so that was something we wanted to do and that was something we got done last week and hopefully we can build on it this week.

"Every day is routine now, you go in and throw with the guys. You even talk about things that you see that they might not see to try and get on the same page, so it's becoming routine and becoming a habit and we are gelling together."

The Bills travel to the New Orleans Saints this weekend.
