CHICAGO -- Chicago Bears right tackle Kyle Long expressed confidence in quarterback Jimmy Clausen's ability to take over for injured starter Jay Cutler.

“We have to have practice reps with Jimmy and that will come this week,” Long said Tuesday on ESPN 1000’s “Carmen and Jurko Show.” “We’ll see how this goes. We are confident in Jimmy.”

ESPN NFL Insider Adam Schefter reported on Monday that Cutler is expected to miss at least two games because of strained hamstring, and that Clausen will start Sunday versus the Seattle Seahawks. The Bears declined to comment on the report.

Clausen replaced Cutler at the 2:51 mark of the second quarter in Chicago’s 48-23 loss to Arizona. He finished the game 14 of 23 for 121 yards and one interception for a quarterback rating of 56.6.

Long said the Bears had to adjust to Clausen’s cadence at the line of scrimmage.

“That was probably the most difficult part and that’s a quick fix,” Long said. “When you hear Jay’s voice all the time, and Jay is the guy giving you all the calls, and Jay is the guy at the line of scrimmage, Jay is the guy at practice and meetings; and then you get a guy Jimmy in there who has knowledge of the offense and the same understanding of the scheme and the gameplan, but the one thing that is different is his voice. One thing that is the same every play is that every play starts with somebody’s voice.

Long added: “We’ll be in the silent count I’m sure in Seattle.”

The two-time Pro Bowler was upset about the amount of penalties racked up the by the offensive line in Week 2. The Bears have to play a much cleaner game for Clausen to have a shot in Seattle on Sunday.

“We understand that it falls on us as an offensive line,” Long said. “We have to get rid of these pre-snap penalties. We can’t be deterring ourselves like that.”
