The Cardinals wide receiver has 405 receiving yards and four touchdowns from the first six games of the 2013 season.
The free safety told the Seahawks' website: "Larry is a great competitor. He's a very professional guy. It's a reason he's had so much success in this league.
"He's a nice guy. He gives you nice compliments on the field. I just don't look at him. I say, 'Alright, if I catch you coming across the middle I'm going to try and do what I have to do'.
"He's a great guy off the field, but it's a business and I'm ready to play. You're always trying to find the ultimate competition. And that's the ultimate competition right there."
Last time the teams played, the Seahawks beat the Cardinals 58-0.
