Former Detroit Lions cornerback Nevin Lawson appears to be facing a four-game suspension. Lawson sent out a tweet Monday night explaining that the league has suspended him for the first four games of the 2019 season because he unknowingly ingested Ostarine, a banned substance by the NFL.
“Despite being very cautious about what I put into my body, I discovered that a test determined that I ingested something that is on the NFL’s banned substance list,” Lawson said via Twitter. “Specifically, the substance is Ostarine, which I have never knowingly taken.
Though Lawson says he didn’t mean to take the banned substance, he still took responsibility for the mistake.
“Unfortunately, it does not matter, as I am responsible for knowing every single ingredient that goes into my body, and I apparently failed in this regard.”
Lawson spent five season with the Detroit Lions after the team selected him in the fourth round of the 2014 draft. After the Lions cut him back in March, he signed a one-year deal with the Oakland Raiders.
Lawson is the second former Lions player to be facing a suspension for the 2019 season. Golden Tate is appealing his four-game suspension after he tested positive for a substance he claims was from a fertility drug.
Though Lawson will miss the first four games—assuming his suspension holds—he will be eligible to face the Lions in Oakland’s Week 9 matchup against his former team.
