The Jaguars have signed veteran CB Aaron Glenn to a 1-year contract and they have released G Tutan Reyes to make room on the roster for him.  Glenn played in all 16 games last season for the Dallas Cowboys and he made 22 tackles, defensed 7 passes and had 1 interception.  Glenn has now played in 196 NFL games in his career and he has made 616 tackles, has defensed 162 passes, has 40 interceptions (5 returned for TDs), had 1 sack and forced 5 fumbles.  The Jags will likely use Glenn as their nickel back this season.
