ENGLEWOOD, Colo. — The Broncos' blind-side protector is staying in Denver.

Denver has signed tackle Garett Bolles to a four-year extension through 2028, the Broncos announced Thursday.

Bolles, who was set to become a free agent following the 2024 season, is the longest-tenured player on the Broncos' roster and is now poised to remain with the team in 2025 and beyond.

The 20th-overall pick in the 2017 NFL Draft, Bolles has started all 112 games in which he has appeared during his career. He has started all 13 games this season and 30 consecutive contests dating back to the start of 2023. Bolles earned second-team Associated Press All-Pro honors following the 2020 season. The Utah product has started the fifth-most games by a Broncos tackle in franchise history and could move into a tie for second by the end of the 2025 season.

In his 13 starts this season, Bolles has allowed just one sack and 24 quarterback pressures across 476 pass-blocking snaps. According to the NFL's Next Gen Stats, Bolles' 4.9 quarterback pressure percentage and 0.2 sack percentage are the second-best marks among tackles with at least 200 pass-blocking snaps this season.

Following the extension, all five starters on the Broncos' offensive line are under contract for the 2025 season. Guard Quinn Meinerz signed an extension with the team in 2024, as he inked a four-year extension that also runs through 2028.

In addition to Bolles and Meinerz, the Broncos signed cornerback Pat Surtain II and outside linebacker Jonathon Cooper to long-term extensions in recent months.
