Adam Thielen Announces NFL Retirement After 13-Year Career, 'Forever Grateful'

Veteran wide receiver Adam Thielen announced Wednesday he's retiring from the NFL.

"What a ride it has been!" he said on Instagram. "13 years what a blessing! Have been blessed with so many great relationships and mentors over the years that I am forever grateful for!"

The two-time Pro Bowler split the 2025 season with the Minnesota Vikings and Pittsburgh Steelers, catching 19 passes for 186 yards in 16 games.

Thielen had a storybook career in every sense of the word.

The native of Detroit Lakes, Minnesota, and a star at Minnesota State, he signed with the Vikings as an undrafted rookie out of college. His profile was so low that he didn't receive an invitation to work out at the 2013 NFL Scouting Combine.

The Vikings took a flier on Thielen, in part because of his hometown connection. Once he arrived at the team's rookie minicamp, he started to turn heads.

"Watching him get in and out of his breaks, it's just like you see today, said Leslie Frazier, who coached Minnesota at the time, in an interview with ESPN's Courtney Cronin. "It'd look like he's covered, but he still finds a way to make the catch, understanding angles, how to come back to the football, his route running. That's what stood out. For a guy that's real slight, he just had a way of being able to set defensive backs up and create separation. And that's not always the No. 1 thing receivers can do — find ways to create separation. A lot of guys rely on pure speed or they rely on strength, but Adam was a good route runner even then. He understood how to set up defensive backs, and that stood out."

Thielen didn't make his NFL debut until 2014 and didn't become a regular part of the Vikings passing game for another two seasons.

The 2016 campaign was Thielen's breakout. He caught 69 passes for 967 yards and five touchdowns. A pair of 1,000-yard seasons followed that.

A sustained drop in his production led Minnesota to cut the 6'2" wideout in 2023, and he proceeded to have his third 1,000-yard season with the Carolina Panthers that year.

While he's not the most decorated pass-catcher in Vikings history, he's likely to be a favorite among fans for a long time. He ranks fourth in franchise history in receptions (542) and fifth in receiving yards (6,751).
