Chris Gamble has been put on injured reserve. Having missed the last two games with a shoulder injury, it was apparently determined that he have surgery now and get ready for the 2013 season, anticipating that the shoulder wasn't going to get better without surgery. Gamble, the team’s best DB, had (per profootballfocus.com) a QB rating in the 60s and had a league leading yards per route run of 0.45.
Beason, a team captain, had looked solid coming off Achilles surgery from 2011, before starting to show wear and tear, and having both a shoulder (left, labrum tear) and knee (right,cartilage cleanup) issue that started affecting play on a high level. At current, it’s hard to say that either issue would cause longterm issues.
It could be said that the season would give Beason time to rest the Achilles injury, and time to more properly rehab the other injuries. It does cast doubt, however, to overall durability – fairly or unfairly – in that he has played a total of 6 games in two seasons.
