Arron Mosby Bio
Arron Mosby, born April 13, 1999, in Fresno, California, is an American professional football defensive end for the Green Bay Packers of the National Football League (NFL). Standing 6 feet 3 inches tall and weighing roughly 248 pounds, he plays on the defensive line and contributes on special teams. Mosby signed with the Carolina Panthers as an undrafted free agent in 2022 and joined the Packers in 2023, where he continues to develop into a rotational pass rusher.
After converting from cornerback to defensive end during his college career at Fresno State, Mosby earned recognition as one of the top edge rushers in the Mountain West Conference. His combination of length, speed, and special-teams value has allowed him to remain active in the NFL despite going undrafted.
Early Life and Background
Arron Mosby was born and raised in Fresno, California, where he attended Sanger High School. At Sanger, he was a two-way starter, lining up at wide receiver on offense and cornerback on defense. He earned all-league recognition twice as a defensive back and was selected as a first-team all-Central Mother Lode Athletic Conference player in 2016. That same year, Mosby was named a Fresno Bee all-star.
Coming out of high school, Mosby was regarded as a versatile athlete with the frame to add weight and the footwork to stay in coverage. His background as a defensive back gave him rare hips and change-of-direction skills that would later help him transition to the edge in college.
Path to American Football
Mosby committed to Fresno State University and quickly found a role on special teams as a true freshman, appearing in all 14 games and recording five tackles. As a sophomore in 2018, he added 12 tackles and one interception, returning a pick 95 yards for a touchdown against San Jose State. The return was the fourth-longest in Fresno State history at the time.
By his junior season in 2019, Mosby had become a reliable presence in the secondary, finishing fourth on the team with 78 tackles, including 40 solo stops. After the 2020 season was shortened by COVID-19, the NCAA granted athletes an extra year of eligibility, and Mosby chose to return for a fifth year. He moved to defensive end in 2021, started 12 of 13 games, and produced 40 tackles, six sacks, six forced fumbles, two recoveries, and a team-leading 15.5 tackles for loss. His performance earned him honorable-mention All-Mountain West Conference recognition and invitations to both the Hula Bowl and the NFLPA All-Star Game.

The Panthers elevated him to the active roster for Week 1 against the Cleveland Browns and again for Week 2 against the New York Giants, where he made his NFL debut, appearing on 16 special teams snaps.
Mosby was promoted and waived several times during his rookie season, bouncing between the active roster and the practice squad as Carolina managed its linebacking corps. He signed a reserve/future contract with the Panthers on January 9, 2023, but was waived on August 1, 2023.
Carolina Panthers Tenure (2022–2023)

The Panthers signed him to a reserve/future contract in January 2023, signaling their intent to keep him in the organization for another training camp. He was released in early August 2023, clearing the way for his next opportunity.
Green Bay Packers Era (2023–Present)
On August 3, 2023, Mosby was claimed off waivers by the Green Bay Packers.

Mosby’s 2024 preseason finale on August 24 against the Baltimore Ravens proved to be a turning point in his career. He strip-sacked rookie quarterback Devin Leary, a fumble recovered by teammate Anthony Johnson Jr. for a touchdown, and on the very next drive intercepted Leary on a short pass. The performance earned him a spot on the Packers’ initial 53-man roster. During the regular season, Mosby appeared in 16 games and recorded 12 combined tackles, 2 pass deflections, and half a sack while contributing heavily on special teams.
Mosby re-signed with the Packers on an Exclusive Rights Free Agent tender on April 8, 2025.

He was elevated to the active roster for Week 7 and Week 9 before being signed to the active roster on November 4.
Driving Style and Strengths
Mosby brings an edge-rusher’s frame with a defensive back’s athleticism, a combination he developed during his college transition at Fresno State. He shows his best work on special teams, where his open-field tackling and pursuit angles stand out, and he continues to add mass and refinement as a hand-in-the-ditch pass rusher. His length and effort at the point of attack give Green Bay a developmental piece to rotate along the defensive line.
