Starter Jake Locker is currently recovering from a hip injury but reportedly took the majority of reps in practice this week from backup Ryan Fitzpatrick, who has deputised for him in the past two games.
"Ryan is going forward like he is starting and I am sure Jake in his mind is [also]," Munchak told reporters. "Jake wants it. I don't know that he'll be 100 percent honest with us, unfortunately.
"He knows how important he is to team. But he understands what we have to do and he'll go by ultimately what we decide is best, even though he may not agree with us, because there's a lot of football to go this year. We want to make sure we are doing the right thing."
