Cincinnati Bengals fullback Chris Pressley had an MRI on his right knee Friday, according to the Cincinnati Enquirer. Pressley was injured in the first quarter of the Bengals' 34-13 win over the Philadelphia Eagles. He was on crutches after the game. Rookie tight end Orson Charles helped fill in for Pressley in the second half. Cincinnati will try out players for the fullback spot. Charles could also fill that role. One of the players expected to try out is Jourdon Brooks, who was in Bengals training camp. He was released on Nov. 6 after being on the practice squad. The Bengals' next game is Dec. 23 at the Pittsburgh Steelers.
