NFL’s Taylor Lewan Cries On Video Explaining Positive Drug Test

Titans star O-lineman Taylor Lewan straight-up cried on camera Wednesday … and it’s all because he says he accidentally ingested a banned substance that could lead to an NFL suspension.

Lewan — Tennesee’s 3-time Pro Bowl left tackle — is facing a 4-game ban after the NFL says he tested positive for ostarine — a substance that essentially works like anabolic steroids.

Lewan made a video to explain the situation … and adamantly says that while he did NOT knowingly take the substance — he is responsible for it getting into his body.

“I want everybody to know that I’ve never taken this supplement knowingly and I’ve never cheated the game and I never will.”

Lewan says he even took a polygraph test — which he says he passed (and promised to share later on social media) — to prove he didn’t purposely take the drug.

Taylor then began apologizing to his team, and that’s when he got emotional … breaking down in tears.

“It’s just hard,” Lewan says … “I’m sorry to the Tennessee Titans and the fans that I won’t be there for 4 games.”

ESPN’s Adam Schefter reports there’s still a chance Lewan could avoid suspension pending the results of further tests … but Taylor was still apologetic, nonetheless.
