Head coach Mike Munchak told reporters: "We're not really leaning any way, it's just that Jake has done well. He was better today, did everything we wanted him to do, and now we need to spend some time with him, talk as an offense, and decide what we think is best for Sunday
"The good thing is he didn't have a major problem where it was easy to say he can't play. So, at least that's a good thing, but that doesn't mean you're ready to play 70 plays on Sunday either. You kind of have to weigh the other factors, and it's hard.
"I wouldn't think last week at this time we'd be talking about this as much. We were thinking like most people were, and he put himself in that situation. That's a credit to him and the training staff. Like you said, when we saw him hurt that day, we never thought he'd be back this quickly, so we'll see."
