Cornerback Richard Marshall agreed to a one-year deal with San Diego on Friday, according to Pro Football Talk. Marshall was released by the Dolphins earlier in the week, surprising many since he was considered a likely starter in the Miami secondary.
Miami's decision to part ways with Marshall may have been financially-motivated, though the team didn't need extra cap space for new acquisitions. Marshall signed a three-year deal worth $16 million with the Dolphins last year and was owed more than $4.5 million in 2013 under the terms of that contract.
The seven-year veteran was limited by a back injury to only four games in 2012, but he's been relatively healthy throughout his career -- before last year, he had appeared in all of his team's games since 2006. Marshall spent his first five years with Carolina, where he made 46 starts, and then spent a season with the Cardinals before moving on to Miami.
Marshall has amassed 18 interceptions over the course of his career, including a career-high four in 2009.
