The Chicago Bears won't change their quarterback depth chart despite Mitchell Trubisky's impressive preseason debut on Thursday night.

Trubisky went 18-of-25 for 166 yards, one touchdown and a quarterback rating of 103.1 against the Denver Broncos.

"Our depth chart is not going to change after one game," John Fox said. "That's a really good defense our first unit went against, probably one of the top three defenses in the league. You have to look at a lot of different things. I can understand how you guys might think [we could make a change], but we're not going to change a whole lot after one game."

Meanwhile, veteran Mike Glennon went 2-for-8 for 20 yards and a 0.0 passer rating.

"You kind of have to put it in perspective," Glennon said. "Like I said, we're exactly one month out [from the regular-season opener against the Atlanta Falcons]. For me, it's just good to get back out playing. I got to get used to coming out as a starter and playing and being that guy. A couple more preseason games to tune this up and I'm confident we'll do that."
