The Broncos confirmed that the Pro Bowl outside linebacker Chubb will undergo an arthroscopic procedure on his ankle on Wednesday after being assisted off the field on Sunday.
The 25-year-old had been battling a bone spur in his ankle and has now opted for surgery to "clean it up", meaning he will be sidelined for the "foreseeable future".
"I'm going to push everything I can to get back to these games and hopefully it's sooner rather than later," Chubb said.
"My mindset is just going to be attack it 100 per cent every day."
Chubb's timeframe to return will be determined by how the surgery goes, but he is determined to get back this season.
The 2018 Draft fifth pick missed the Broncos' Week 1 game due to the ankle issue as the team's medical staff took a conservative approach, trying to avoid surgery.
"I did everything I could to manage it and to try to come back and play," Chubb said. "The thing [to do] is now just to go in, clean it up and be right back.
"I know these guys are going to do everything they can to make that playoff push, and I'm going to be right there with them.
"We're 2-0 … and I know these guys are doing everything they can to keep that win streak going. I just wish I could be a part of it. But I know I'm going to be back on the back end of it and making that playoff push. I'm excited about that."
The linebacker posted 12 sacks in his rookie season in 2018, but injuries have curtailed his progress leaving him frustrated.
Chubb missed two games in 2020 with an injured right ankle, as well as 12 in 2019 with a torn anterior cruciate ligament.
According to ESPN's Adam Schefter, Miami parted with the 2023 first-round pick they received from the San Francisco 49ers in the trade that facilitated the Niners moving up in the 2021 draft to select quarterback Trey Lance third overall.
In addition, the Dolphins sent a 2024 fourth-round pick and running back Chase Edmonds in exchange for Chubb and a 2025 fifth-round pick.
The Dolphins will hope Chubb can provide a significant boost to a defense that has allowed 5.89 yards per play, the seventh-most in the NFL, and tallied 14 sacks for negative yardage, only good enough for a five-way tie for 20th.
Their pressure rate of 39.6 per cent is above the NFL average, but Chubb will be tasked with improving Miami's ability to convert those pressures.
This season the 2018 first-round pick has registered 5.5 sacks, eight quarterback hits, four tackles for loss and two forced fumbles for a stellar Denver defense, the efforts of which have been wasted by continued poor performances on offense.
Denver beat the Jacksonville Jaguars in London last Sunday to improve to 3-5, still a hugely disappointing record for a team that had hoped to make the leap after sending five picks, including two first-rounders, and three players to the Seattle Seahawks for nine-time Pro Bowl quarterback Russell Wilson.
But the struggles of the Wilson-led attack created talk of them being sellers at the trade deadline. No team will be able to make trades after 16:00 EST on Tuesday.
Such speculation proved accurate, with the 5-3 Dolphins landing a pass rusher who is tied 10th in adjusted sack rate among players with at least 50 edge snaps, according to Stats Perform data.
Chubb figures to form an imposing duo with second-year edge rusher Jaelan Phillips, whose pressure rate of 27.6 per cent is the fifth-best in the NFL for edge rushers (minimum 50 snaps).
The Dolphins face the Chicago Bears in Week 9 at Soldier Field, where Chubb could make his debut.
Following the move for Chubb, the Dolphins also struck a deal with the 49ers for running back Jeff Wilson Jr, sending a fifth-round pick to San Francisco.
