Tennessee Titans sixth-round safety Robert Johnson has agreed to terms on a contract.

Johnson tweeted the news on Wednesday.

A three-year starter at the University of Utah after transferring from L.A. Southwest College, Johnson totaled 155 tackles, including 5 for a loss, with 13 interceptions and 26 total passes defensed.

Johnson twice earned All-Mountain West Conference honors, including first-team in 2009 after posting a team-high six interceptions.

The 6-2, 203-pound Johnson is an exceptional athlete with a knack for making plays on the ball. Johnson will compete for a back-up safety job with the Titans, with his special teams play likely the determining factor towards earning a spot on the Titans' 53-man roster this season.

Once Johnson signs, the Titans will need to make a roster move to fit him on the 80-man roster. First-round defensive end Derrick Morgan and third-round wide receiver Damian Williams remain unsigned, with the Titans opening training camp on July 31.
