One thing the Raiders do not need right now is an injury to one of their stalwart offensive linemen. Their right side of Trent Brown, Gabe Jackson, and Rodney Hudson is where they are supposed to not have to worry. Now there is reason to worry.
Shortly into practice, Gabe Jackson pulled up limp and was unable to put weight on one of his legs and would ultimately need to be carted off the field. Carts taking people off the practice field is always a big concern. When it happens to a crucial starter, that concern is heightened.
