The Miami Dolphins have signed fourth-round pick RB Lamar Miller, the team announced Monday. Miller's deal covers four years.

A two-year letterman and one-year starter with the Hurricanes, Miller played in 23 career games with 13 starts. He recorded 335 carries for 1,918 yards (5.7 avg.) with 15 touchdowns and caught 28 passes for 181 yards (6.5 avg.) and one score. Miller also added 15 kickoff returns 376 yards (25.1 avg.) and a touchdown and three punt returns for 16 yards on (5.3 avg.).

Born April 25, 1991 in Miami, FL, Miller attended Killian High School where he was a first team All-State selection as a senior. He led Miami-Dade in rushing with 217 carries for 1,749 yards and 22 touchdowns.

Miller (5-10, 212), who ran well during February's NFL Combine (40-yard dash times of 4.40/4.41), dropped a bit in the draft due to a lack of playing experience and he doesn't appear as explosive on tape as his statistics would otherwise indicate, according to a NFL personnel source.

Miller joins a crowded backfield which now has seven players under contract.
