Pederson says Logan's calf spasm is better, though he was held out of practice

Eagles coach Doug Pederson said Friday that defensive tackle Bennie Logan suffered a "left calf spasm" in practice Thursday that will make him the only Eagle listed as "questionable" heading into Sunday's game at Detroit.

Pederson said Logan was "feeling much better" Friday morning but would not practice in the 3-0 Birds' final tuneup before taking on the 1-3 Lions. If Logan can't play Sunday, Pederson said, Beau Allen will start.

After practice, Logan was not available to reporters, but Allen said he is ready to shoulder as much of the load as necessary. He also seemed to think that given Logan's reputation for toughness -- Logan has appeared in 49 of a possible 51 games since arriving as a third-round draft pick from LSU in 2013 -- Logan is likely to play.

The Eagles practiced indoors Friday, despite the beautiful weather, so the coaches could pipe in noise to simulate conditions at domed Ford Field. Rookie quarterback Carson Wentz hasn't played in an NFL dome yet. Pederson said the Birds' silent-count work has gone very well.

"It's hard on the tackles and tight ends" who are farthest from the center, Pederson said. "Because it's all based on head movement or taps ... I thought that this week, and even leading up to the Bears game, we've handled it well ... You could almost do the whole season in 'silent,' even your home games, because you're so used to doing it that when you go back to your normal cadence it's a little weird sometimes to hear a live voice ... We're able to mix a lot of different, multiple snap counts, even in the silent count."

Other tidbits from the coach's final media availability before the game:

*Pederson said he thinks players returned from their early bye week in the right frame of mind. "I think they've really handled it well this week; energy's been great all week long, very spirited, which you love to see, coming off the bye ... I think they understand that it's still a long season. They're excited, obviously, for where we are, but by no means are they satisfied by just being 3-0. The goal, obviously, is to win the next game."

*Pederson said he thinks running back Ryan Mathews, who didn't play after the first quarter of the Steelers game because of an ankle problem, healed well during the bye and should be more effective against the Lions.

*Pederson lauded the contribution of backup quarterback Chase Daniel in preparing Carson Wentz. "He's also sort of a calming presence for Carson on the football field and in games," Pederson said.

*Pederson lauded Jordan Matthews' leadership of the Eagles' young leadership group.
