Jack Cochrane Bio
Jack Cochrane (born February 9, 1999) is an American professional football linebacker for the Kansas City Chiefs of the National Football League (NFL). Standing 6 feet 3 inches tall and listed at 236 pounds, he plays a physical, downhill style on the defensive side of the ball. Cochrane signed with the Chiefs as an undrafted free agent on May 1, 2022, and has since won back-to-back Super Bowls with the franchise. He wears jersey number 43 for Kansas City.
A former walk-on who developed into a tackling leader at the University of South Dakota, Cochrane earned First-team All-Missouri Valley Football Conference honors in 2021 before breaking into the NFL. His path from a small Iowa high school to championship Sundays in the NFL has made him a notable depth and special teams contributor for one of the league’s most consistent contenders.
Early Life and Background
Jack Cochrane was born on February 9, 1999, in Mount Vernon, Iowa, where he grew up and attended Mount Vernon High School. The small eastern Iowa community, located near Cedar Rapids, provided the backdrop for his early development as both an athlete and a student. Cochrane came from a supportive Midwestern environment that encouraged multi-sport participation and competitive play.
At Mount Vernon High School, Cochrane competed in football and developed into a college-level prospect at linebacker, where his combination of size and instincts stood out. He was teammates with future NFL offensive lineman Tristan Wirfs during his high school years, and the two later faced each other on professional fields. After completing his prep career, Cochrane received an opportunity to play college football at the University of South Dakota.
Path to American Football
Cochrane committed to the University of South Dakota, joining the South Dakota Coyotes program as a member of the 2017 recruiting class. He spent five seasons with the program, taking advantage of the extra year of eligibility granted to college athletes in 2020 due to the COVID-19 pandemic. The additional year allowed him to grow into a more complete linebacker and a defensive leader for the Coyotes.
Across his college career, Cochrane developed into one of the more productive tacklers in the Missouri Valley Football Conference. In his final collegiate season in 2021, he finished with 103 tackles and earned First-team All-MVFC recognition, building on a Second-team All-MVFC selection from 2019. His production and senior-season accolades drew attention from NFL scouts, even though he was not among the top-rated prospects at his position nationally.
Jack Cochrane Career
Early Career (2022)
After going unselected in the 2022 NFL Draft, Jack Cochrane signed with the Kansas City Chiefs as an undrafted free agent on May 1, 2022. The Chiefs saw value in his size, college tackling production, and special-teams potential, inviting him to compete for a depth role. He was waived on August 30 as part of final roster cuts but was quickly re-signed to the team’s practice squad the following day.
Cochrane did not remain on the practice squad for long. On September 13, 2022, he was signed to the Chiefs’ active roster, marking his official entry onto a 53-man NFL roster. His first professional appearances came on special teams, where he made a quick impression with his tackling and pursuit angles.
Kansas City Chiefs Breakthrough (2022–2023)
Cochrane’s rookie season ended at the highest level possible. He won Super Bowl LVII when the Kansas City Chiefs defeated the Philadelphia Eagles 38-35, recording one tackle in the championship game. Although his role was limited primarily to special teams and rotational defensive snaps, the rings earned as a rookie laid a foundation for his NFL résumé.
In his second professional season, Cochrane helped the Chiefs win a second consecutive championship when Kansas City defeated the San Francisco 49ers 25-22 in Super Bowl LVIII. Becoming a back-to-back champion as a young reserve further cemented his standing within a deep Kansas City linebacker room and special teams unit.
Kansas City Chiefs Era (2024–Present)
Following the second Super Bowl win, Cochrane re-signed with the Kansas City Chiefs on March 11, 2024, to continue his role with the organization. His 2024 season, however, was interrupted on December 23, 2024, when the Chiefs placed him on injured reserve due to an undisclosed injury, cutting his playing time short.
On April 11, 2025, Cochrane re-signed with the Chiefs on a one-year, 2.1 million dollar contract, signaling the team’s continued confidence in his special-teams value and locker-room presence. Through his first several NFL seasons, his statistical line includes 62 total tackles, one fumble recovery, two pass deflections, and one interception, reflecting steady contributions in rotational duty.
Driving Style and Strengths
On the field, Cochrane plays with the downhill, physical approach that defined his college career. He reads plays quickly, closes on ball carriers with leverage, and shows reliability in open-field tackling, attributes that translate well to special-teams coverage units. His size at 6-3 and 236 pounds allows him to take on blockers and disengage in tight quarters, while his instincts help him diagnose run fits.
Notable Events and Milestones
Cochrane’s signature milestones include his back-to-back Super Bowl titles following the 2022 and 2023 seasons, won as a member of the Kansas City Chiefs. He also reached his first NFL active roster in September 2022 after a brief practice-squad stint, and his First-team All-MVFC season in 2021 stands as the college milestone that paved his professional pathway.
Jack Cochrane Career Wins
Jack Cochrane’s professional résumé is anchored by two Super Bowl championships, both earned during his first two NFL seasons with the Kansas City Chiefs.

Kansas City Chiefs Highlights
Cochrane’s most prominent highlight remains Super Bowl LVII, where the Chiefs rallied past the Philadelphia Eagles 38-35, followed by Super Bowl LVIII, a 25-22 victory over the San Francisco 49ers. Across those championship runs, he recorded tackles in the biggest games of the NFL calendar while contributing to coverage units throughout the postseason.
Other Wins and Performances
Beyond his Super Bowl rings, Cochrane earned First-team All-MVFC honors in 2021 and Second-team All-MVFC recognition in 2019, both reflecting his consistency as a tackler and team leader at South Dakota. His college production, including 103 tackles in his final season, foreshadowed the special-teams reliability he has offered in the NFL.

2025 Season Performance
Entering 2025, Jack Cochrane is in position to continue his role as a depth linebacker and core special-teams player for the Kansas City Chiefs after re-signing on a one-year, 2.1 million dollar contract in April 2025. Coming off an injured-reserve stint late in 2024, his health and availability will shape his early-season usage as the team sorts out its linebacker rotation. The Chiefs remain among the AFC favorites, and Cochrane’s championship experience provides steady locker-room value.
Defensively, Cochrane is expected to compete for snaps behind established starters while retaining a leading role on multiple special-teams units. His career totals of 62 tackles, one interception, two pass deflections, and one fumble recovery through 2025 demonstrate the kind of stat line that keeps reserve linebackers on the field in key situations.
Looking ahead through the 2025 campaign, Cochrane’s objectives include staying healthy, expanding his defensive responsibilities, and contributing to another potential deep postseason run with Kansas City. With a winning culture and familiar coaching staff around him, he has a clear path to extend his NFL tenure beyond 2025.
