It was a revolving door at St. Thomas Sports Park Tuesday with the Tennessee Titans making six roster moves including the return of fullback Quinn Johnson.
The Titans signed Johnson after placing Colin Mooney on Injured Reserve with a knee injury. Johnson played 20 games with the Titans in 2011 & 2012, but was cut the day before the Titans opener with Pittsburgh this season because of a quad injury.
Michael Griffin also returned to the roster with his one week suspension over.
The Titans also added veteran tight end Visanthe Shiancoe. Craig Stevens and Delanie Walker are both trying to come back from concussions. Stevens missed last week's game and Walker was knocked out of it in the first half when his head hit the turf.
The Titans waived linebacker Zac Diles and defensive back Shann Schillinger. The team still has one remaining roster spot and is expected to add a tight end this week.
