Bears keeping an eye on Khalil Mack’s right ankle

The Bears will continue to monitor outside linebacker Khalil Mack’s right ankle, which he hurt in the first half Sunday. Mack missed 16 snaps against the Dolphins. He played much of the rest of the game with the ankle taped up.

Mack didn’t seem too concerned about it after the 31-28 overtime loss, which was easily his worst performance with the Bears after four stellar games.

“I’m good,” he said.

Coach Matt Nagy said Monday, though, that Mack would undergo routine testing at Halas Hall “in the next couple of days.”

The Bears went without a sack against Miami. The Dolphins chipped at Mack with tight ends and running backs, but that’s not particularly exotic.

“As most teams do, there’s an emphasis on being able to do some different things with those edge guys, both Leonard [Floyd] and Khalil,” Nagy said. “And so they did some stuff there.”

Cornerback Prince Amukamara left the game with an injured left hamstring, the same injury that chased him from the Cardinals game and forced him to miss the Buccaneers game.

“I don’t know if you’d call it a recurrence,” Nagy said. “I just think, for him, it was similar. Yeah, it wasn’t anything new.”

‘Offense is growing’

Quarterback Mitch Trubisky had a few stellar second-half moments — and some duds — but Nagy was impressed by the scoring drive that put the Bears up 28-21 with 3:17 to play in regulation.

“That’s a big moment for our guys to step up,” he said, “especially after losing a little of that momentum when they tied it up and got the two-point conversion. You go right down, and a big third down you hit for a touchdown. That’s the growth of an offense. And our offense is growing right now, and I like it.”

The 29-yard touchdown pass to rookie receiver Anthony Miller came against an eight-man front.

“They were going to try to [bring the heat] up there — or at least disguise it — and our offensive line did a great job of protecting Mitch,” Nagy said. ‘‘Those guys ran their routes right, and Mitch made a good throw.”

This and that

Nagy reiterated that he wouldn’t have asked tight end Trey Burton to do “one thing different” on the pick play that got him whistled for offensive pass interference.

† He also said an unusual personnel grouping two plays before the Bears’ field-goal try was to get some “bigger people” on the field. Wide receiver Josh Bellamy and tight ends Dion Sims, Ben Braunecker and Burton were on the field to block for backup running back Benny Cunningham, who gained four yards on a run.

Cunningham played five offensive plays, Braunecker eight.

“Nothing too out of the ordinary,” Nagy said. ‘‘It was pretty safe.”
