The Jaguars have signed 26-year old TE Martin Rucker off of the Dallas Cowboys’ practice squad. Rucker played in 1 game for the Cowboys this year but he didn’t catch any passes. Rucker has now played in 11 games in his first three years in the NFL and he has caught 2 passes for 17 yards (8.5 avg). Rucker will try to replace Zach Miller who was placed on I.R. yesterday, ending his season. To make room on the roster for Rucker, the Jaguars have placed 22-year old CB Rod Isaac on the Injured Reserve List due to a hamstring injury. Isaac played in 3 games for the Jaguars this year but he didn’t have any tackles.
