The Dolphins released linebacker Philip Wheeler and guard Shelley Smith, according to the Miami Herald, while punter Brandon Fields restructured his contract, taking a pay cut after a down year in 2014.
The release of back-up lineman Smith creates a bigger hole in an already weak area of the Dolphins' depth chart. The move suggests Miami's front office has a plan to address the interior offensive line, which was a liability in 2014.
Meanwhile, the team announced they re-signed linebacker Kelvin Sheppard, defensive tackle Derrick Shelby and safety Michael Thomas.
