Andrew Luck has said that he expects to face a "physical" and "fast" Seattle Seahawks defense this weekend.
The Indianapolis Colts' opponents this weekend are without a defeat in nine regular season games, and have one of the top-ranked defenses in the NFL.
The Colts quarterback told the team's website: "These guys are definitely good. [Cornerback] Richard [Sherman]'s got incredible ball skills. I think they have seven interceptions on their team already. Three of the guys in the secondary have two apiece.
"They're all physical [and] fast. They have all the attributes. Not just fast, they can also catch the ball. They're also big. They do a great job in press [coverage]. They do a great job off [the ball].
"Our receivers know what they're going up against. I have all the faith in the world in them. They'll run great routes. As an offense, one of our big goals is no turnovers every week. We know that gives us a chance to win."
The Colts have won three of their four games so far this season.
