The Pittsburgh Steelers have signed linebacker Blake Martinez off the Carolina Panthers practice squad and onto their 53-man active roster, per ESPN's Adam Schefter.
The 29-year-old Martinez has played seven NFL seasons (2016-2022). He retired after playing four games with the Las Vegas Raiders in 2022 to sell Pokemon cards through his company Blake's Breaks.
According to documents reviewed by CNBC Make It reporter Megan Sauer, the company brought in $6.5 million in revenue on the collectible reselling platform Whatnot.
Zak Keefer of The Athletic reported Blake's Breaks then had more than $11 million in earnings in the last year.
