Mitch Trubisky took reps with members of the Bears' first-team offense on Wednesday, the first time the No. 2 overall pick worked with the team's top unit in practice since being drafted in April.
The Bears have, to this point, been steadfast in giving all first-team reps to Mike Glennon, who signed a three-year, $45 million contract in March. But while Trubisky received those first-team reps Wednesday, Glennon will still be the team's starter against the Tennessee Titans on Sunday.
Coach John Fox said there's been "no change in our quarterback depth chart."
Trubisky will play with the first-team offense in the all-important third preseason game this weekend, though. Glennon will play the first half, while Trubisky will begin the third quarter with the rest of the first-team offense.
Fox said the Bears want to get a "true evaluation" of Trubisky and added this plan is something the team discussed for a while. Mark Sanchez remains the Bears' backup, per Fox.
