NFL Media Insider Ian Rapoport reported McCain agreed to a two-year deal worth $5 million.
McCain was released by the Miami Dolphins earlier this offseason after one disappointing season in which he was frequently picked on by opposing quarterbacks in 11 starts.
The Titans' signing makes sense as McCain has experience in Dick LeBeau's defense. The 5-foot-9 corner appeared in 14 games, with nine starts, for the Steelers in 2014 when LeBeau was still in Pittsburgh.
McCain will provide depth for Tennessee's back end and likely spend most of his time at the slot in sub-packages.
