Cornerback Brent Grimes, who missed almost all of last season with an Achilles tendon injury, has signed a one-year contract with the Miami Dolphins.
Grimes started 28 games for the Atlanta Falcons in 2010-11 but was hurt in the opener last year. He was undrafted and broke into the NFL with the Falcons in 2007.
Grimes, who has 13 career interceptions, will compete for a starting job with the Dolphins. They lost Sean Smith via free agency to the Kansas City Chiefs.
