CHICAGO -- The body-language police likely focused a critical eye on Jay Cutler during Chicago’s 20-14 loss Sunday to the Detroit Lions, but behind the scenes, the benched quarterback spent extra time at Halas Hall preparing Jimmy Clausen for his first start since his rookie season with the Carolina Panthers in 2010.

“He was involved during the week in the meetings, actively and vocally involved,” Bears coach Marc Trestman said of Cutler. “Today, he did what you would expect him to do. He was with Jimmy and [quarterbacks coach] Matt [Cavanaugh] between series and was part of the dialogue.”

Clausen threw two touchdown passes and an interception, with a passer rating of 77.0. But with just two days of prep time, Clausen said Cutler and rookie David Fales stayed with him until nearly 9 p.m. those nights at the team’s facilities.

When Clausen signed with the team in June, Cutler immediately took the backup quarterback under his wing.

“We only had two days to prepare for this game, so we stayed pretty much until 8:30 p.m. every single night, trying to watch as much tape as possible, get all the calls down,” Clausen said. “Get everything down to make sure we were prepared for this game. But Jay was great. David Fales was great in helping me to go through all the calls, watching the film. Staying real late, they helped me out a lot.”
