Offensive lineman Todd Herremans was with the team when the Eagles played in Denver in 2005, but he didn't play. When he worked out before the game, he noticed the altitude at the onset but soon became comfortable. Defensive end Trent Cole said the Eagles are prepared for the altitude.
"We got oxygen tanks by the benches and backups, so you can't think about that," Cole said. "Who thinks about breathing out there anyway?"
Kelly wasn't worried about it, either. It's more of a discussion point than a legitimate concern for the Eagles.
"It's an anaerobic sport," Kelly said. "It doesn't affect you the way you think. We're not going there to run a marathon. I think a lot of it is mental and it's not as big a deal as people make it out to be."
Long and short
Broncos quarterback Peyton Manning remarked after Monday's win over the Raiders that it was "nice of the NFL to give Philly 12 days and us six."
It is actually 10 days for the Eagles, but it's true that the Eagles have a long week and the Broncos have a short week.
Eagles cornerback Cary Williams smiled when he heard Manning's comment and said the veteran quarterback was trying to play mind games. Kelly had little reaction, saying the Eagles would play whenever, wherever.
"We played three games in 11 days. We don't control the schedule," Kelly said. "We only care about what we can control."
New on the corner
The Eagles had new cornerback Roc Carmichael at practice on Tuesday wearing No. 21. Carmichael was signed off the Houston Texans practice squad last week.
"I think it's a great opportunity because I feel like the team, with new coaches and a new system offensive and defensively, is at a point of growth," Carmichael said. "We all can grow together."
Carmichael, 25, was a 2011 fourth-round pick by the Texans. His first season was hindered by injury, and he's since been caught in a numbers game.
Chung still out
Patrick Chung was the only player to miss Tuesday's practice. Chung has a shoulder injury.
