In week 9, the Lions traveled to Seattle, Washington to take on the Seattle Seahawks. The Lions took an early lead in the first quarter, scoring 17 unanswered points. First came 2 TD's: a Brandon Pettigrew 7-yard catch, then a Bryant Johnson 29-yard catch, and afterward was a 41-yard field goal. The Seahawks responded in the second quarter with a TD and 2 field goals. First the TD, a 3-yard run by Julius Jones. The field goals by Olindo Mare were both from 37 yards out. In the 3rd quarter came another Seattle field goal, from 24 yards out. Then a Seahawks TD to give them the lead, a 2-yard TD catch by T.J. Houshmandzadeh. However, the fake field goal for a 2-point conversion was no good. The Lions' only score of the second half was a 50-yard field goal. The Seahawks sealed their win with a 61-yard interception for a TD by Josh Wilson.
