PHILADELPHIA (973espn.com) - The Eagles will be without a significant defensive starter when they face the unbeaten Minnesota Vikings on Sunday.

Doug Pederson confirmed that nose tackle Bennie Logan has a "significant'' groin injury and is  "week-to-week'' moving forward.

The last time Pederson used that terminology it was in regard to Zach Ertz’s rib injury after the season opener against the Cleveland Browns. Ertz ended up missing two games and returned after the team’s bye week so his shelf time was three weeks.

Logan played in just 17 snaps before incurring the injury in the loss to Washington on Sunday and will be replaced by Beau Allen, who played well in 43 reps against the ‘Skins.

Interestingly Allen is a Minnetonka, Minn. native and will be getting his third career start against his hometown team. Rookie Destiny Vaeao, who did not play well against Washington, will also move up to third in the defensive tackle rotation.

Pederson also reported four other less significant injuries coming out of Sunday’s game. Center Jason Kelce (foot), cornerback Ron Brooks (calf), linebacker Mychal Kendricks (rib) and defensive end Marcus Smith (groin) are all expected to be held out of practice Wednesday but the coach expects all to be ready for the 5-0 Vikings.
