Isaac Seumalo took the first-team snaps at right tackle during practice Wednesday, making the rookie third-round pick the fifth Eagle to play that position this season with the starters.

Seumalo is viewed by the team as an interior lineman, but injuries forced him to tackle. Allen Barbre did not practice because of a hamstring injury, Halapoulivaati Vaitai (knee) remains out, Matt Tobin (knee) was placed on injured reserve, and Lane Johnson is suspended until next week.

Coach Doug Pederson is hopeful that Barbre will return for Sunday's game against the Baltimore Ravens. Because Barbre is a veteran, Pederson said he "doesn't need a ton of reps" to play. If Barbre is not healthy, Seumalo will start.

"He had a little bit way back in the spring, if that's any indication," Pederson said of Seumalo's experience at right tackle. "He's been more guard. He's gotten some [practice at] tackle on the service team going against our defense and things like that over the past couple weeks. But obviously, nothing with our offense."

Seumalo played guard, center, and tackle at Oregon State. The Eagles liked his versatility when he was drafted, but they would have played him at right tackle sooner if they thought he had a future at the position. At this point, the Eagles can't worry about his future. They just need to worry about Sunday - the only other option is undrafted rookie Dillon Gordon, who converted from tight end a few months ago.

"Last time I checked, the NFL was all about making things as hard as possible, putting you in high-stress situations," Seumalo said. "It's all good in the long run. Just got to stay healthy and do my job."

The changes put a strain on quarterback Carson Wentz, who continues to play behind jumbled offensive lines. If Seumalo starts Sunday, it would be the sixth starting combination on the line in 14 games this season.

"You can't let it affect you, one, and two, we've had great guys step up," Wentz said. "Obviously, last week we had guys shuffle all around. But I thought they did a great job. I thought they all stepped up in their role. But it's tough when you don't get those opportunities during the week to be together - right tackle working with the right guard, those sorts of things."

More injuries

In addition to Barbre and Vaitai, the Eagles missed wide receiver Jordan Matthews (ankle) and running back Darren Sproles (concussion) at practice. Matthews is expected to play Sunday. Sproles is still in the concussion protocol. . . . Wide receiver Dorial Green-Beckham returned to practice after missing last week with an oblique/abdomen injury. Tight end Brent Celek practiced with a stinger.
