MIAMI -- The Miami Dolphins added depth to their receiver group by signing free-agent Damian Williams Thursday to a one-year, $800,000 contract, a source told ESPN.com.

Williams, 25, is a former third-round pick of the Tennessee Titans in 2010. He caught a career-low 15 receptions for 178 yards in 10 games last season.

The Dolphins are searching for healthy veteran wide receivers to add depth behind starters Mike Wallace and Brian Hartline. Backups Brandon Gibson (knee) and Armon Binns are both coming off season-ending knee injuries.
