Tuesday, the Dolphins reached agreements with second-round offensive tackle Jonathon Martin and seventh-round receiver Rishard Matthews, the third and fourth members of their 2012 draft class to sign with the team.

There he would replace retired veteran and 2011 turnstile Marc Colombo to shore up a weak right side of the line. His athleticism makes him a perfect fit in the zone-blocking scheme that Joe Philbin plans to run.
Matthews is a possession receiver who has a knack for making the catch in traffic. He was extremely productive in two seasons at Nevada, catching 147 passes for 2,243 yards and 13 touchdowns.
Fellow rookie and sixth-round pick B.J. Cunningham will both be fighting for a roster spot in Miami's thin receiving corps. They will face competition from journeyman Legedu Naanee and undrafted free agent out of Texas A&M Jeff Fuller, who has the distinct advantage of being familiar with Mike Sherman's offense.
Both deals are for four years, and Martin's deal is reportedly worth just under $5 million. Financial terms of Matthews' contract were not disclosed.
