The Dolphins are $19 million over the 2018 salary cap and need to reduce payroll before the new league year starts March 14.
Miami is expected to release or restructure contracts with tight end Julius Thomas and linebacker Lawrence Timmons but its biggest cap hit could be out the door.
According to the Miami Herald, the Dolphins will consider releasing five-time Pro Bowler Ndamukong Suh, who is guaranteed $8.5 million if he's still on the roster by March 19. Designating the 31-year-old defensive tackle as a post-June 1 cut would free up $17 million. Either option is in play for Suh, who has a cap hit of $26.1 million this upcoming season.

Suh has recorded 15 1/2 sacks and 181 tackles in three seasons in Miami and hasn't missed a game since 2011. If the Dolphins let Suh walk there will be a plethora of teams with plenty of cap space vying for his services.
