On Thursday, the NFL announced three-game suspensions of Buccaneers receiver Antonio Brown, Buccaneers safety Mike Edwards, and free-agent receiver John Hamilton III. The man who first broke the story of fake vaccination cards in Tampa explains how the league concluded that this trio was misrepresenting their vaccination status.

According to Rick Stroud of the Tampa Bay Times, the NFL used Stroud’s original report from November 18 as the template for constructing its investigation.

On Wednesday, November 24, NFL investigators contacted Steven Ruiz, Brown’s former live-in chef who went public with the claim that Brown had secured and used a fake vaccination card after Brown allegedly failed to pay Ruiz’s bill. Offered an opportunity to have an attorney on the line before answering questions, Ruiz agreed to be interviewed “without hesitation” and then shared his story with the league. Ruiz told the investigators that Franklin sold Brown his fake card.
