In preparation for their Sunday afternoon matchup against the Cowboys, the Philadelphia Eagles have announced that four players will be ruled out for the game. G Cam Jurgens, CB Bradley Roby, RB Boston Scott, and Grant Calcaterra will all be sidelined for the upcoming matchup.

Jurgens, who has been dealing with a foot injury, has missed the last four games while on Injured Reserve. Although his 21-day practice window was opened this week, he was only able to participate in a limited capacity and is not yet ready to return to action. The Eagles anticipate his comeback after the bye week on November 20th against the Chiefs.

With Jurgens out, the Eagles are expected to start rookie third-round pick Tyler Steen at right guard. This will mark Steen's first career start, and he has been working with the first-team offense throughout the week. Veteran Sua Opeta, who has been the starter in the last four games, will step aside for Steen's opportunity.

Bradley Roby, the Eagles' cornerback, will miss his third consecutive game due to a shoulder injury. Despite not being placed on the Injured Reserve list, the Eagles had hoped for Roby's return prior to the four-week mark. There is a possibility that he may come back in the game against the Chiefs.

Boston Scott, the running back, has been unavailable for practice all week due to a personal matter. As a result, veteran Rashaad Penny is expected to take his place in the lineup against the Cowboys.

Grant Calcaterra, who has been progressing through the concussion protocol, is not yet ready to make a return. However, his limited participation in Friday's practice indicates positive progress. With his history of concussions in college, the Eagles are taking the necessary precautions before allowing him back on the field. In the meantime, Albert Okweugbunam will likely be active for the second time this season.

The Eagles will have to adjust their lineup accordingly with the absence of these key players. Despite the setbacks, the team remains focused on their upcoming game against the Cowboys and will look to extend their winning streak. Stay tuned for further updates on the Eagles' roster and their quest for victory.
