In recent years the Titans have spent many of their free-agent dollars on players who were Colts; David Thornton, Nick Harper and Jake Scott all made the move from Indianapolis to Nashville.
This season there has been some movement of less prominent players in the other direction.
After signing defensive tackle Antonio Johnson off the Titans' practice squad on Nov. 4, the Colts now intend to add Titans practice squad tight end Jamie Petrowski to their 53-man roster, Jim Wyatt is reporting.
The Colts have made no announcement. But chances are it ties in with the shoulder injury that has held rookie Tom Santi out of the last three games.
