Miami Dolphins bolster secondary with 3-year deal for former Arizona Cardinals CB Richard Marshall 

By Post Staff

The Dolphins finished a long day of tryouts and negotiations by signing six-year veteran defensive back Richard Marshall to a three-year contract.

Marshall, 27, provides versatility and a veteran presence to the Dolphins’ defensive backfield, which finished 25th in pass defense in 2011. A former 2006 second-round pick for Carolina, Marshall has 500 tackles, 17 interceptions and seven sacks in six NFL seasons with the Panthers and Cardinals. The total value of his contract is $16 million with $6 million guaranteed, according to ESPN’s Adam Schefter.

Marshall (5-11, 198) will likely replace veteran free agent Will Allen as the Dolphins’ Nickel cornerback, but he also has played outside cornerback and excelled last year as a free safety in Arizona. Marshall also serves as insurance for young cornerback Sean Smith, who is entering the fourth and final year of his rookie contract.

Marshall was the Dolphins’ second signing of the day, hours after Paul Soliai completed a two-year deal to remain in Miami. The Dolphins also hosted right tackle Eric Winston, offensive lineman Artis Hicks and outside linebacker Jamaal Westerman for visits.
