Veteran cornerback Greg Toler visited the Dolphins on Friday although no deal has been reached yet.
Toler, a 2009 fourth-round draft pick, spent his first four seasons with Arizona and the last three with Indianapolis.
Last year, he had 51 tackles but did not have an interception and was graded by Pro Football Focus 106th of 111 cornerbacks.
The Dolphins still need a cornerback to start opposite Bryon Maxwell, who replaces Brent Grimes as the team’s No. 1 corner.
Cornerback could be a top priority with four players who could potentially be selected by Miami in the first round — Florida’s Vernon Hargreaves III, Clemson’s Mackensie Alexander, Ohio State’s Eli Apple and Houston’s William Jackson III.
