Former Dallas Cowboys offensive lineman Isaac Alarcon has been suspended by the NFL for six games, the league announced. Alarcon should be a familiar name to the fans who watched Dallas' season of Hard Knocks on HBO.

The 26-year-old Alarcon is part of the NFL’s International Player Pathway Program and hails from Monterrey, Mexico.

Alarcon, who now plays for the San Francisco 49ers, was suspended for violating the league’s policy of performance-enhancing substances.

"As a result of this, I used a protein that I included in my routine a couple of times, with total ignorance that it contained a 'prohibited substance' by the league, which was detected in the last test I recently had. I humbly accept this mistake and I fully understand the sanction that was granted to me, which I promise never to commit again, since I will pay more attention to the supplements that I will use in the future."
