Jaguars placed WLB Clint Session (concussions) and DE John Chick (knee) on reserve/PUP. Session sustained three concussions in 2011 and had a severe one in college. Much like Jahvid Best and Austin Collie, he's wisely exercising extreme caution now. The Jags will be forced to roll with Russell Allen at weak-side linebacker. He had 38 tackles, one interception and two forced fumbles in six starts last season.
