The cornerback believes that the NFC West champions have a strong selection of passing options for quarterback Colin Kaepernick.
The 30-year-old told reporters: "We respect their receivers. They have a good core of receivers. We know we are going to have our hands full.
"This is what you expect when you play in the NFC Championship game, you expect the best of the best. We're definitely ready for the challenge."
"If we give creases up, [Kaepernick] can take a play that looks like a broken play, what looks like we have a play that's covered up pretty well, and he can turn it into a 70-yard touchdown run."
The two sides meet at the Georgia Dome on Sunday.
