Delmas, 28, started 12 games for the Dolphins in 2014 before tearing his ACL and finishing the year on injured reserve. He signed with the Dolphins in March 2014 on a one-year, $3.5 million deal after five seasons with the Detroit Lions, and received another one-year contract from the Dolphins despite his season-ending injury.
A second-round pick in the 2009 NFL Draft, Delmas burst on to the scene as one of the best rookies of the 2009 class and earned alternate spots to the Pro Bowl in 2010 and 2011. Despite signing a two-year contract with the Lions worth $9.465 million before the 2013 season, he was released after starting 15 games for the Lions that year.
Delmas suffered the injury in a joint practice with the Carolina Panthers, which also featured second-year wide receiver Kelvin Benjamin go down with a knee injury. Delmas was working in coverage against former Dolphins wide receiver Ted Ginn Jr.
