The Miami Dolphins have an off day on Wednesday before their third organized team activity on Thursday. As the team continues its build-up toward June’s minicamp and July’s training camp, we continue with day two of our look at the team’s roster. The return of our 90-in-90 series yesterday featured cornerback JuJu Brents. Today, we stay on the defensive side of the ball with a closer look at an undrafted free agent rookie.
Miami is rebuilding the edge rushers this year, having moved on from veterans
Bradley Chubb and Jaelan Phillips. Chop Robinson is the center piece for the group, but behind him the team is counting on free agents and rookies to step up this season. Could an undrafted rookie crack the lineup and make an impact? Mason Reiger is hoping so.

Reiger missed all of the 2024 season with a knee injury. He transferred from Louisville, where he played three seasons before the year off. In 2025, the move to Wisconsin gave Reiger a chance to prove he was healthy and ready for the NFL. His 4.78-second 40-yard dash, 40-inch vertical jump, and 10-foot, 5-inch broad jump backed up his health status. Reiger also participated in the 2026 East-West Shrine Bowl and was selected the defensive MVP.
Draft profile via Lance Zierlein, NFL.com:
Reiger is a tall, linear edge rusher with a slender frame. He doesn’t look like a pro pre-snap, but he certainly plays like one after the snap. He lacks the size/anchor to consistently set the edge and can be controlled when tackles latch on, but he’s unusually talented to work off contact for quick wins at the point of attack. He’s a short-striding rusher who takes similar tracks at similar speeds and is more pressure-creator than sack-finisher at this time. However, altering his approach (tempo and angles) and adding a better inside counter could create a bump in his sack production. Reiger needs more mass and refinement but could become a good rotational odd-front edge in time.

2026 expectations
Reiger was projected to be anywhere from a fifth- to seventh-round draft pick this year, but instead landed among the undrafted. He comes into Miami knowing there is a pathway, not just to make the roster, but to see a large amount of playing time with the edge-rusher rebuild happening in South Florida. The injury history may have led to him going undrafted, but going undrafted has Reiger ready to play with a chip on his shoulder.
“I felt like I deserved to be picked, but I think that’s part of, you know, everything happens for a reason,” Reiger told the Palm Beach Post’s Joe Schad during the team’s rookie minicamp. “And I’m super blessed to how my story’s played out. And this is just another opportunity for me to prove all these coaches right that took a chance on me and prove everybody wrong that didn’t believe in me. You know, obviously, the fact that I wasn’t drafted shows that I haven’t done enough. So that’s just another mindset push for me to keep going.”
Reiger may need some refinement on his pass rush moves at the NFL level, but he never quits and he has shown he is healthy. Now it is just a matter of moving from being overlooked in the draft to fighting his way onto the roster.
Every year, there seems to be a breakout undrafted free agent signing that makes the Dolphins roster. This year, with the team in rebuild mode, there may be more than one UDFA who finds himself on the 53-man roster in Week 1. Reiger could absolutely be one of those players.
