The Titans have placed 31-year old linebacker David Thornton on the reserve/PUP list which will cause him to miss at least the first six weeks of the season.  Thornton played in 11 games for the Titans last season and he made 59 tackles, had 1 sack and he forced 1 fumble.  Thornton has played in 58 games (55 starts) in his four years with the Titans and he has 366 tackles, 2 sacks, 17 passes defensed, 2 interceptions and 6 forced fumbles.  This is a big loss for the Titans as Thornton is one of the better linebackers on the team.
