On a telephone call with "NFL Live" host Trey Wingo shortly after the midnight dawn of the free-agency signing period, Dansby announced his first visit will be with the Dolphins on Friday.
Dansby was the Arizona Cardinals' leading tackler last year with 109. He recorded one sack, five tackles for losses and one forced fumble.
The Dolphins have identified inside linebacker as a high priority to address this offseason. They have been disappointed with the play of Channing Crowder and Akin Ayodele, who combined for one sack, one interception and zero forced fumbles in 2009.
