In a bold move that sends ripples through the AFC landscape, the Kansas City Chiefs have fortified their roster depths with two strategic signings to the practice squad on December 16, 2025. Even as the football world holds its breath over Patrick Mahomes’ season-ending surgery, the Chiefs are refusing to fold, instead striking back by adding offensive lineman Nick Broeker—a former seventh-round pick of the rival Buffalo Bills—and safety Tanner McCalister, who recently suited up for the AFC West foe Denver Broncos. This calculated reinforcement underscores Kansas City’s unrelenting pursuit of dominance, signaling to rivals that the dynasty isn’t crumbling just yet.
The signings, first reported by Chiefs Digest beat writer Matt Derrick on X, fill the voids left by guard CJ Hanson and safety Mike Edwards, both recently elevated to the active 53-man roster. Derrick noted, “Chiefs have signed guard Nick Broeker and safety Tanner McCalister to the practice squad. They fill the slots vacated by CJ Hanson and Mike Edwards.” These additions come amid ongoing workouts with other prospects, as confirmed by NFL insider Aaron Wilson, who detailed a list of 10 players tried out by the team, including Broeker and McCalister.
Broeker, a 6-foot-4, 305-pound guard who just turned 25 in October, brings much-needed depth to an offensive line plagued by injuries and inconsistencies throughout the 2025 season. Drafted by the Bills in the seventh round of the 2023 NFL Draft, he never saw game action in Buffalo but appeared in 12 regular-season contests with the Houston Texans, logging nine offensive snaps and 53 on special teams. His college pedigree at Ole Miss, where he protected notable talents like New York Giants quarterback Jaxson Dart and Cleveland Browns running back Quinshon Judkins, adds intrigue to his potential role. With the Chiefs’ starting offensive line performing solidly when healthy but faltering due to absences, Broeker represents a fresh option to bolster the trenches and protect whoever steps in under center.
On the defensive side, McCalister—an undrafted free agent since 2023—offers versatility and grit to the secondary. Standing at 5-foot-11, the soon-to-be 26-year-old split his college career between Oklahoma State and Ohio State, amassing 149 tackles, four interceptions, and 13 pass breakups over 62 games. Professionally, he’s bounced between the Cleveland Browns and Broncos, appearing in six games primarily on special teams with 91 snaps there and just 19 on defense, tallying nine tackles. Scouting reports from NFL Draft Buzz highlight his aggressive tackling and physicality at the line, though he’s been flagged for penalties and overzealous play. The Chiefs, who likely scouted him during his 2024 stint with Denver, see untapped potential in refining his game for special teams contributions.
These moves unfold against the backdrop of Mahomes’ devastating injury news. The superstar quarterback underwent season-ending surgery earlier this week, but as of December 17, the Chiefs have yet to place him on injured reserve—a procedural step that would free up a roster spot, potentially for practice squad quarterback Chris Oladokun. Head coach Andy Reid has hinted that Oladokun could back up Gardner Minshew for the remainder of the season, though the team retains flexibility to elevate him without using Mahomes’ spot immediately. This “Mahomes Watch” has fans and analysts on edge, but Kansas City’s proactive signings demonstrate a front office unwilling to let adversity derail their playoff aspirations.
For AFC rivals like the Bills, Broncos, and beyond, this is a stark reminder: the Chiefs are adapting, not retreating. By poaching talent from divisional and conference competitors, Kansas City is making a shocking statement of resilience. As the 2025 season hurtles toward its climax, these under-the-radar additions could prove pivotal in maintaining the edge that has defined the Chiefs’ era. Beware, indeed—the kingdom is fortifying its walls.
