The Kansas City Chiefs signed cornerback Sean Smith, the team announced Friday.

Smith signed a three-year deal worth $18 million, including $11 million guaranteed, a source told ESPN NFL Insider Adam Schefter. His addition solidifies the cornerback spot opposite Brandon Flowers.

In addition to Smith, the Chiefs on Friday also signed former Minnesota Vikings offensive lineman Geoff Schwartz.

Smith, who was the Miami Dolphins' top cornerback, had 12 passes defensed, two interceptions and three forced fumbles last season.

The 25-year-old Smith has five interceptions and 40 passes defensed in 63 career games.
