Cornerback Chris Culliver will reportedly sign a four-year contract with Washington, making him the fourth 49ers free agent to find a new home since the opening of free agency.

Culliver started a career-high 14 games last season and had his best season with four interceptions. He was returning from a torn ACL that kept him out of action the entire 2013 season.

A third-round pick in 2011, Culliver started 20 games and appeared in 46 games in three seasons. He was the team’s No. 3 cornerback in his first two full seasons.

Washington also hosted 49ers free-agent cornerback Perrish Cox on a visit this week. Cox met with the Cleveland Browns on Thursday and is scheduled to visit with the Tennessee Titans on Friday.

Earlier this week, running back Frank Gore signed with the Indianapolis Colts, guard Mike Iupati joined the Arizona Cardinals, and outside linebacker Dan Skuta reached a deal with the Jacksonville Jaguars.

Culliver’s agreement was first reported by the NFL Network. CBS Sports reports Culliver will make “upwards of $8 million” per season.

The 49ers have expressed an interest in re-signing veteran free-agent cornerback Chris Cook, but they have not engaged in any recent discussions, a source told CSNBayArea.com. Cook appeared in six games with the 49ers last season before sustaining a season-ending hamstring injury.
