Dartmouth lineman Delby Lemieux signs with Vikings as undrafted free agent

Delby Lemieux’s path from Duxbury High School to the NFL crossed one of football’s least-traveled roads, then ended with Minnesota. The Vikings agreed to terms with the Dartmouth offensive lineman as one of 19 undrafted free agents, giving the 6-foot-5, 305-pound tackle a shot in Eagan after a senior season that put him on the national radar.

For Dartmouth, the signing capped a four-year run that began with an unranked recruit and ended with one of the Ivy League’s most decorated linemen. Lemieux finished his career in the fall of 2025 after earning Associated Press first-team All-America honors, along with Phil Steele second-team and Stats Perform third-team recognition. He also played in the 2026 Panini Senior Bowl on Jan. 31 in Mobile, Alabama, where he lined up against top Power Four competition and showed he could belong in that conversation.

The Vikings made the move official at 7:27 p.m. on April 25, announcing a group of 19 undrafted free-agent signings that included Lemieux. Dartmouth also confirmed the deal in its own release, marking the next step for a player who kept climbing after arriving in Hanover, New Hampshire, from Duxbury, Massachusetts.

Lemieux’s appeal was always bigger than the box score. Scouting reports pegged him as a tackle with the frame to play inside at the next level, noting his heavy punch, strong anchor and the kind of functional power that can translate in the pros. The same reports also pointed to length and agility questions at tackle, which helps explain why Minnesota may view him as a developmental interior option rather than a pure edge protector.

That profile fits the kind of move teams make after the draft, when they look for traits, not just pedigree. Minnesota has also shown a willingness to mine FCS talent, and Lemieux arrives with a résumé that goes well beyond a standard camp body. He was a co-winner of Dartmouth football’s Jake Crouthamel Award and previously received the Charles “Stubby” Pearson Award in 2024 for character, leadership on campus, high academic standing and performance on the field.

Dartmouth’s 2025 team went 7-3 and produced 12 All-Ivy honorees, with Lemieux among the seniors recognized as the program closed a strong season. From Duxbury to Hanover to a chance in Minnesota, he now gets the rare opportunity to prove that an Ivy League lineman can hold his own at the NFL level.
