ENGLEWOOD, Colo. — As the Broncos approach their second preseason game, Head Coach Vance Joseph did not reveal whether Von Miller would play on Saturday against the Bears.

"We'll see," Joseph said. "We'll see with Von. Last year he didn't play until Week 3 and he had four plays, one sack, one quarterback pressure. He did OK. So we'll see."

The other players on the starting units, though, should see more time than they did in a short stint against the Vikings.

"We're going to play quite a bit," Joseph said. "Not too much where we expose guys, but we're going to play. We have to play. We played about six or seven snaps last week on offense and about 14 on defense. So I'm looking at about a quarter, quarter and a half with our ones. Our twos will play until we see progress. We'll play our threes late."

At least one other starter could miss Saturday's game. Chris Harris Jr. missed his second straight practice as he recovers from an oblique injury.

Joseph said he is hopefully Harris will be ready for Saturday.

"He's day to day," Joseph said.

Joseph also provided updates on Shamarko Thomas, Menelik Watson and Troy Fumagalli:

· Thomas left the field during practice because of the heat.

"He's been here for two days and obviously took a lot of reps today, so just heat," Joseph said.

·Watson underwent an MRI on Thursday morning to determine the extent of his pec injury.

"We'll see what the results say there," Joseph said.

· Fumagalli continues to deal with soreness that stems from an offseason sports hernia surgery.

"He is really sore, so we're being smart with his injury," Joseph said. "It goes back from the spring. We're being smart with Troy."
