Trestman said Wednesday that he's optimistic Cutler will be recovered enough from his high-ankle sprain to start in Week 15.
Cutler has been cleared to practice at full speed and will participate Wednesday. If his ankle passes a "thorough" test in the workout, he will get the green light. If not, McCown will start for another week.
Trestman plans to make an announcement on this week's starter by Thursday.
