The Seattle Seahawks are still on top.

After finishing training camp with no major setbacks, the defending Super Bowl champions stayed in first place in the latest power rankings from the Associated Press. The Denver Broncos had one vote from the 12-person panel in the Pro32 poll released Tuesday.

The Seahawks will have their status tested right away, with the NFL opener Thursday against Green Bay. The Packers were fourth, one spot behind the New England Patriots.

San Francisco saw the most notable slip, from one first-place vote in the preseason poll six weeks ago to sixth. The 49ers offense was sluggish in exhibition action, and a nine-game suspension of star outside linebacker Aldon Smith became official.
