Quindarius Dunnigan’s 2026 Jaguars DE Battle

Who Is Quindarius Dunnigan?

The Jaguars added the 6‑foot‑3 edge rusher, who sports jersey No. 59, as an undrafted free agent after the 2026 draft. Dunnigan spent four campaigns at Middle Tennessee State before moving to Michigan State for his final two college seasons. The Michigan State stint produced a breakout year, with 21 pressures and five sacks in the most recent season.

That output marked a sharp rise from his prior two years, when he recorded only six pressures and a single sack in 2024, even though he received 65 extra pass‑rush snaps. PFF’s run‑defense grades have been solid, and he was praised for his tackling work in 2025. Over his college career he posted 26 tackles for loss from 104 attempts, showing the ability to shed blocks consistently.

Dunnigan’s college résumé includes a blend of pass‑rush productivity and run‑stopping reliability, traits the Jaguars will look for in a depth piece. His background at two different programs gives him varied tactical experience, which could be valuable in the NFL’s complex offensive schemes.

Roster Hurdles Ahead

Making the 53‑man roster will be a steep climb for the rookie. Defensive ends Josh Hines‑Allen and Travon Walker are entrenched as the opening‑string pair, and they are joined by Wesley Williams, Danny Striggow, BJ Green, and Zach Durfee in the competition hierarchy. That is six players vying for limited spots, though the Jaguars showed last season they are comfortable carrying six edge defenders.

Fellow undrafted signee Bryan Thomas Jr. has already distinguished himself during offseason drills, setting a high bar for the competition. Dunnigan’s best‑case scenario appears to be a spot on the practice squad in Year 1, given the depth surrounding him. The Jaguars’ willingness to keep extra defensive ends opens a slight window, but the rookie will need to earn every snap.

From a scouting perspective, Dunnigan’s upside lies in his pass‑rush potential and run‑defense grade, which could earn him future roster spots if the Jaguars expand their defensive line rotation. The 2026 campaign will be a proving ground for whether his college production translates to the professional level.

What It Means for the Jaguars

If Dunnigan can develop into a reliable pass‑rush contributor, he could alleviate pressure on the Jaguars’ interior line and provide depth for injuries. Even a practice‑squad stint could free up practice‑squad spots for other prospects, maintaining roster flexibility. The Jaguars’ approach of carrying six edge defenders suggests they value a deep pool of pass‑rush talent.

The competition will push all six players to improve, potentially reshaping the defensive line hierarchy before training camp ends. Dunnigan’s journey will serve as a case study for undrafted prospects seeking to carve out a role in the NFL. Fans can expect an intense battle that could decide the final shape of Jacksonville’s pass‑rush corps.
