Hoping to improve their secondary and looking for cornerback talent, the Miami Dolphins are signing free agent cornerback Chris Culliver, per an NFL source.

Culliver was a signature free agent acquisition of the Washington Redskins in the spring of 2015, signing a four-year, $32 million deal. But on September 14 of that year, he was suspended for one game for violating the NFL's personal conduct policy following misdemeanors that occurred in March 2014. In November he tore his ACL and MCL and was placed on injured reserve.

The Redskins decided bringing Culliver back for a second season was not financially feasible when they signed former Carolina Panthers cornerback Josh Norman in April and drafted Virginia Tech cornerback Kendall Fuller in the third round.

It is unclear how close to playing Culliver is following his reconstructive knee surgery. The Dolphins obviously want a close look at that.

He is just 27 and was productive enough with the San Francisco 49ers to draw significant interest in free agency in 2015 from the Redskins and other teams.

Culliver, 6-foot and 200 pounds, is in his fifth season and has started 26 games. He has seven career interceptions.

Culliver visited with the Dolphins the past few days which suggests the team is comfortable with his health. The club has cut and added a handful of cornerbacks since training camp began two weeks ago.

[Update: The contract is for one year, heavily laden with incentives should Culliver win a starting job, which given the team's cornerback situation is a possibility at least for some games this season.]
