LEXINGTON, Ky. (AP) - Kentucky players know what they'll get Saturday from No. 20 Mississippi State - defensive pressure.

The Bulldogs (4-0, 1-0 Southeastern Conference) rank in the top 15 in several defensive categories, including first in turnover margin (plus 12). They are physical up front, and senior cornerbacks Johnthan Banks and Darius Slay (seven combined interceptions) lead a veteran secondary.

Mississippi State just doesn't know which Kentucky quarterback it will be defending.

Freshmen Jalen Whitlow and Patrick Towles will rotate under center for the Wildcats (1-4, 0-2) with starter Maxwell Smith out due to an ankle injury. Towles will make his debut while Whitlow makes his first start.

Bulldogs senior strong safety Corey Broomfield says Mississippi State hopes the Kentucky QB situation creates ``a lot of chances to make plays on the ball.''
