Outside linebacker Leonard Floyd fractured his right hand in Saturday night's 24-23 preseason win over the Broncos and underwent successful surgery Sunday.
The Bears remain hopeful that the 2016 first-round draft pick from Georgia will be able to play in the Sept. 9 regular-season opener against the Packers at Lambeau Field.
"We're staying optimistic for Green Bay," said coach Matt Nagy.
Floyd sustained the injury late in the first quarter when he was cut blocked and fell forward, bracing himself with both hands on the ground.
"It was just kind of unlucky," Nagy said.
The Bears coach revealed that Floyd likely will have to wear something to protect his broken hand during games.
"I don't think it's going to be healed," Nagy said. "I think he's going to have to end up playing through it. It might require something in regards to having a cast or a club-type deal. There's been evidence of guys that have had that and been productive, and that's what we're hoping right now."
Nagy said that Floyd remains in a good frame of mind after the procedure.
"He's staying positive," said the Bears coach. "He's in good spirits. The surgery went well for him, as good as it could go. So now it's just a matter of having the right mindset and recovering from the surgery and staying in it mentally."
Nagy knows that Floyd's injury could have been much worse.
"It's a relief I think because you're always concerned about season-ending injuries," he said. "So for us to feel optimistic of where he's at after that happening, I guess you could say that's positive."
Floyd has dealt with injuries since being selected by the Bears with the ninth overall pick in the 2016 draft. He missed four games as a rookie due to a calf injury and two concussions and sat out the final six contests last year with sprained knee ligaments.
In other injury news, Nagy said that tight end Adam Shaheen sustained a sprained right ankle against the Broncos and was in the process of being evaluated. Asked whether the second-year pro would be able to play in the season opener against the Packers, Nagy said: "We're not sure there yet exactly, [but] we're hoping. We'll probably know more later today after the tests come back. He's literally in the test as we speak."
