This is Hanson's 12th player of the week award. He trails Adam Vinatieri and John Carney, who both have 13, for most all-time.
In Sunday's win, which improved the Lions to 2-3 on the season, Hanson connected on a 45-yard field goal in overtime to give Detroit its first victory at Philadelphia since a 13-11 win at Veterans Stadium November 16, 1986.
"It was a must win," said Hanson after the game. "Playing 20-plus years in the league and you go out there, you know that it's more than just a kick for that game.
"I was nervous because we need it. We need it bad. We fought our way back and we have been close a couple times this year and we hadn't come through.
"We needed it for that reason and we needed it to get our season on track. We've done that."
It wasn't just his kick in overtime that helped Detroit to the win. Hanson made four field goals on the day, including kicks from 46, 34, 19 and 45 yards.
Add in his two extra points and Hanson was responsible for 14 of the team's 26 points.
"I don't know what the other guys were thinking, but I'm sure I'm not the only one who realized we had to have this win and to go 1-4 would be huge to overcome," said Hanson.
"It was a big win. And the good thing is everybody knows we have a lot of work to do because we barely pulled it out. A win's a win in the NFL and we needed it."
Hanson is currently fourth among NFL kickers in scoring with 58 points. He has connected on 16 field goals (17 attempts) and 10 PATs.
With his first field goal on Sunday, Hanson moved past John Carney (2,062) into third on the NFL's all-time scoring list.
He finished the game with 2,074 career points.
"Obviously as a pro you learn to buckle it down and while you feel that little bit of anxiety, still perform," said Hanson of his game-winner. "You just kind of realize you're the only person they sent out there to do it and do your job.
"Obviously it's great to have Nick (Harris) and Don (Muhlbach), and I wasn't thinking anything other than hitting the ball and it was a great hold and it went in."
