Sean Smith Signed

The Dolphins have signed another of their 2009 draft picks, with second-round selection Sean Smith agreeing to a four-year contract, according to agent David Canter's Twitter page.

The 61st overall selection in the 2009 draft, Smith was named first-team All-Mountain West Conference last fall after recording five interceptions.

According to Canter, his deal includes a 12.5 percent increase in signing bonus and a 6.5 increase in guaranteed money over the 61st overall selection in the 2008 draft, tight end Martellus Bennett, picked by Dallas.

Smith would be the sixth of the Dolphins' nine picks to sign, following Patrick Turner, Brian Hartline, John Nalbone, Andrew Gardner and J.D. Folsom.

The only remaining picks to be signed are first-round choice Vontae Davis, second-rounder Pat White and fifth-round selection Chris Clemons.
