In a statement released through the NFLPA, Jones apologized and blamed the violation on an unnamed supplement.
The safety's full statement:
"I recently learned from the NFL that I tested positive for substance that is banned under the NFL performance enhancing substances policy. 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. I am very sorry for the effect of my mistake on my teammates and coaches. I apologize to them, the Dolphins organization, and fans. During the time away from the team, I will participate in an intense training program so that I can help my team as soon as I return."
Jones is a fifth-year player out of Georgia. Last season he recorded 84 solo tackles, 1.5 sacks and one interception, which he returned for a touchdown. In 2012, he tallied four interceptions, nine passes defended and two forced fumbles.
Jones had started every game for the Dolphins in each of the last two seasons. Prior to the 2013 season, the Dolphins signed Jones to a four-year extension.
