The  Jaguars are working to add depth to their secondary before the upcoming NFL Draft.  In that effort, S Gerald Sensabaugh, out of North Carolina, signed a tender offer with the Jags last Tuesday.  Sensabaugh was a restricted free agent and is now entering his fourth season with the team after being drafted in the fifth round in 2005.  He has started 11 games for the Jaguars.  In playing 34 games, Sensabaugh has totaled 86 tackles, two interceptions, one forced fumble and recovery, and 17 special teams tackles.  Sensabaugh was placed on the injured reserve in mid-September after suffering a shoulder injury in Week 2.
