The Jaguars signed DT Corvey Irvin to the active roster and placed WR Brian Robiskie on injured reserve with a hamstring injury.
Irvin, a third-round pick of the Panthers in 2009, spent his entire rookie season on I.R. He has been on the Jaguars' practice squad the past six weeks.
Robiskie played in six games with the Browns earlier this season, catching three passes.
The Jags also signed WR Charly Martin to the practice squad.
