The Miami Dolphins have activated safety Reshad Jones, the team announced today. Jones had been on the exemption list as he served a four game suspension for failing a drug test. That suspension ended following the team's Week 4 win over the Oakland Raiders, with Jones able to return to the team for practice.

The Dolphins had their bye week last week, so activating him was not required until this week.

No corresponding roster move was required to make space for Jones after the Dolphins suspended defensive lineman Derrick Shelbyearlier in the day. Shelby was arrested on October 4 for trespassing and resisting arrest without violence at a Fort Lauderdale club.

Since being selected in the fifth round by the Dolphins in 2010, Jones has appeared in 60 games, starting 46 of them. He has 7 career interceptions, 5.5 sacks, 1 touchdown, 2 forced fumbles, 3 fumble recoveries, 19 passes defensed, and 279 tackles.

Defensive back Jimmy Wilsonhad been starting at safety in Jones' absence, and will likely move back to the nickel cornerback position he played last year.
