Marz was signed to Tennessee's active roster Saturday, John Glennon of The Athletic reports.
Marz joins a Titans squad in dire need of offensive line depth, with Jack Conklin (knee - ACL) and Taylor Lewan (concussion) both out for Week 2, and Dennis Kelly (illness) considered questionable. The 26-year-old is likely to play a rotational role on Tennessee's O-line against the Texans on Sunday.
Marz was waived by the Chargers on Tuesday, Ricky Henne of the Chargers' official site reports.
Marz was signed of the Titans' practice squad in late September but was an inactive in all six games for the Chargers. He was waived in order to make room for Jeff Cumberland and Denzel Perryman (ankle) on the active roster.
