The Detroit Lions have shown interest in former San Diego Chargers cornerback Antoine Cason during NFL free agency.

According to Cleveland.com, the Lions and Browns are interested in Cason. The Lions spoke with Cason's agent, but it is currently unclear how strong Detroit's interest is. Cason cannot speak with Lions coaches, or members of management, until Tuesday at 4 p.m.

Cason has started in 45 regular season games for San Diego over the past three years. He had 73 tackles, two interceptions, 11 pass breakups and two forced fumbles last season.

However, Cason is reportedly seeking a contract that will pay him at least $5 million annually in free agency.

Detroit is examining its options at cornerback because Chris Houston and Jacob Lacey are unrestricted free agents, while Bill Bentley and Chris Greenwood are recovering from season-ending injuries sustained in 2012.
