Matt Eberflus discusses how much starters will play in first preseason game, injuries, Roquan Smith & more

Injury update: Eberflus confirmed that receiver N’Keal Harry underwent ankle surgery Thursday but did not provide a timetable for his return. The Bears coach added that receiver David Moore “will be out for a bit also” with a lower leg injury he sustained in Tuesday’s Family Fest practice.

Running back David Montgomery and tight end Cole Kmet, both of whom missed Thursday’s practice with undisclosed injuries, remain day-to-day but likely won’t play Saturday.

Eberflus said both players are expected to be fine, adding that Montgomery should be back “pretty fast.”

Bears top draft pick Kyler Gordon, a second-round cornerback from Washington, also remained out of practice Thursday.

“When players miss time on the grass, the actual playing of the game, working on the fundamentals and techniques, that hurts,” Eberflus said. “That hurts our football team and hurts their development.

“We just try to get those guys back as soon as possible, and I tell the players: ‘Your body will tell you when you’re ready. When you’re ready to go, let’s get back out there and let’s go.’ They’re doing everything they can to get back.”

Telescope view: Eberflus is excited about coaching his first game for one of the NFL’s founding franchises, albeit a preseason contest. But he intends to focus solely on the task at hand.

“The first thing to come to mind right there is that you don’t look at the past,” Eberflus said. “You’ve got to focus on the future and what’s ahead of you right now. The way we look at it is you have to have a telescope view as the head coach: where we’re going to get to. And then you have to have a microscopic view of what we’re doing day-to-day.

“I’m just focusing on having good game-day operation, working on the scheme, evaluating the personnel for the first game … That’s the way you function best; you’ve got to be in the moment. You’ve got to be right here, right now.”

A head coach for the first time in his career, Eberflus is confident that he’s ready to make all the crucial…
