The Seahawks won their regular season opener against the Detroit Lions on September 10. Despite the Seahawks' offense failing to score a single point, Josh Brown had a big day, as he provided all of the Seahawks' points.  He kicked a 20-yarder, a 50-yarder, and a 42-yard field goal as time expired to win the game. Meanwhile, the defense limited the Lions to just two field goals. With the win, the Seahawks started out the season at 1-0. On September 11, the Seahawks announced they had acquired wide receiver Deion Branch in a trade with the New England Patriots. In return, they gave their first-round pick in the 2007 NFL Draft to the Patriots.
