The team's starting safety has been suspended four games for violating the NFL policy on performance enhancing substances. The Dolphins are now down two important defenders due to suspension: Dion Jordan was also banned four games for a similar violation.
"I recently learned from the NFL that I tested positive for substance that is banned under the NFL performance enhancing substances policy," Jones said in statement. "I worked closely with the union to investigate what happened and I learned that a supplement I took caused the positive test. I deeply regret not investigating the supplement carefully before I took it, and I will never again take a supplement without having it checked."
Jones was a 16-game starter last season, finishing with 107 tackles, 1.5 sacks and an interception that was ran back for a touchdown. He signed a four-year, $30 million contract last August.
