From what I could gather from press releases and reading various insider sources, both DeShawn and Earl were pulled out of the game with class 1 hamstring pulls, which are relatively mild and with some therapy and workout, both should be good to go on Sunday against the Bucs.
The reason both are class 1 is that the coaching and sports medicine people, had the good sense to yank their butts off the field when the symptoms first started, rather than waiting until we had a full blown class 3 ham string pulls, which we all know can have a player down for weeks.
I hate to keep sounding like a broken record, It seems apparent to me that whoever is responsible for the conditioning of the Seahawk players, is failing the players miserably, by accepting their present state of health and readiness for playing in the NFL as being sufficient.
It's all well and good to want to play at a higher level than your opposition, but that level of execution comes with a price that few athletes are willing to pay. Mediocre conditioning brings about mediocre results. Greatness demands greatness.
If the Seahawks want to stop seeing all these injuries that have been plaguing their team this season, they are going to have to push their players to much higher levels of conditioning. A higher level of conditioning coupled with proper dietary needs will go along ways towards being able to avoid these reoccurring injuries, that will stand in their way and deny them the ability to achieve the goals they have set for themselves.
Short and simple, superior conditioning equals fewer injuries, equals more Super Bowl titles

It's not rocket science,
It is going to take everyone from the top down agreeing that this is the problem and then doing something about it.
If someone in the organization is responsible for insuring the conditioning levels of the athlete that will allow them to perform at their position at absolute maximum levels, and at the same time resist and avoid those injuries that are commonly attributed to not being at that level of physical conditioning.
Then the Seahawks management needs to either require the person/s designated to oversee player fitness, to correct that state of affairs, or replace them with someone who does understand the importance of conditioning as it applies not only to role performance on the field, but also to their ability to resist and avoid injury due to their physical condition.
Go Seahawks !!
