The Tennessee Titans have added yet another free agent.

This one is a familiar face, as the Titans signed defensive tackle Antonio "Mookie" Johnson to a one-year deal on Monday. Johnson was originally drafted by the Titans in the fifth round of the 2007 draft, and spent all of his rookie season on injured reserve with a knee injury.

The Indianapolis Colts then signed him off the Titans practice squad the following season, and he spent five years with them before becoming a free agnet this off-season.

He is the 13th player the Titans have signed this off-season. The Titans also waived undrafted linebacker Tom Wort, who failed his physical due to a hamstring injury.
