Sunday night will be just another day at the office for left tackle Jason Peters.

In the last two weeks, Peters has battled two of the better defensive ends this season in Washington's Andre Carter and New York's Osi Umenyiora. This week, Peters faces a player whom tight end Brent Celek called "the best defensive player in the game" in Cowboys outside linebacker DeMarcus Ware.

"He's a great player. He's one of the best that's ever played his position," Peters said. "I give him his ups. He's worked hard at what he does. He's crafty at that position (which is why) he's one of the best."

The 6-4, 262-pound Ware has 45 tackles, 5.0 sacks, 15 QB pressures and a pair of forced fumbles this season. In his career against the Eagles, Ware has 6.5 sacks and all but one of them have come against Donovan McNabb. The only quarterback Ware has sacked more is New York's Eli Manning.

Peters faced Ware once back in 2007 as a member of the Buffalo Bills. Peters said that he "did all right," but it's not just Peters who will have to contain him this Sunday. The Cowboys have moved him around the line of scrimmage this season to get the best matchup possible.

"They do play him a little bit unexpectedly where you may not plan to see him. That's a game plan thing," offensive coordinator Marty Mornhinweg said. "You try to know where he's at. The one thing I'll say about him is he is a dynamite player. He is fast and quick like a running back-linebacker-receiver-type guy. He's big and strong as well. He's really an elite player in this league and one of the best pass rushers. He had 20 sacks last year."

Although Ware is the only active player to notch 20 sacks in a single season, Peters believes the caliber of players he faced in the last two weeks were just as good.

"I just went against Osi. I had one before that, Carter, he's pretty good. I got Ware this week, so it's a typical week for me," Peters said. "Every week, I've got a challenge. It's no big deal."
