Running back Brandon Bolden was not spotted at the start of Friday morning's rainy New England Patriots practice, which sparked the following question: Could this open the door for Stevan Ridley to return to the 46-man game-day roster? Bolden hasn't been listed on the team's injury report this week and the absence could be non-injury related. More details regarding Bolden's absence should be learned around 4 p.m. Bolden hasn't been on the injury report this week, but has spent time on it earlier this season with a knee injury. Since that decision, one of the top storylines surrounding the team is if Ridley will continue to be a healthy scratch, or if he might re-emerge in some form. Svitek landed on the injury report Wednesday, leaving the Patriots vulnerable at tackle because starter Sebastian Vollmer is on season-ending injured reserve and top backup Marcus Cannon remains out of practice.
