The Miami Dolphins have lost two of the team's starting cornerbacks in 2013.

Earlier this week the Dolphins released often-injured starter Dimitri Patterson, and on Thursday four-year veteran Nolan Carroll signed with the Philadelphia Eagles.

Carroll, a 2010 fifth-round pick who started 27 games for the Dolphins the past four seasons, was being courted by the Buffalo Bills, San Francisco 49ers, Cleveland Browns and the Eagles.

The Dolphins didn't make re-signing Carroll, who contributed 47 tackles, two sacks and three interceptions last season, a priority because the team has some young talents at cornerback the organization feels will develop with playing time.

The Dolphins used a second-round pick on Jamar Taylor, and a third-round pick in the 2013 draft to select Will Davis. Both rookies played sparingly last season because of injuries, inexperience, and Miami's depth at the position.
