LONDON – Left tackle Jason Peters is battling. He's pushing. He's playing at less than 100 percent, he acknowledges, with a biceps injury that he says is "sore, but I can play through it." A nine-time Pro Bowl player who is destined one day to join the greatest of the greats in Canton, Ohio in the Pro Football Hall of Fame, Peters is currently in unfamiliar territory.

He isn't at his best. He isn't at his down-in, down-out dominating form on the field, and that's raised some questions from outside the Eagles organization about Peters and his performance.

Just to be clear, Peters is prepared to give it everything he has to stay on the field despite multiple aches and pains from his knee injury from a season ago and a biceps injury that is still fresh.

"We're trying to win, man, and I'm trying to keep Carson (Wentz) as clean as I can," said Peters, who has been limited in practice all week. "We let one slip away last game (against Carolina). We had them. We just need to play 60 minutes."

Peters had knee surgery last season and worked hard in his rehabilitation to get back on the field for the start of the 2018 season. He didn't play in the preseason as the Eagles wanted to keep him as fresh as possible for the regular season. Peters described his '18 performance as "not playing at the high level that I want," which doesn't mean he's been bad. It just means he hasn't been Jason Peters-esque.

It doesn't happen all at once for any player coming back from a major surgery. He suffered a torn ACL in the Week 7 win over Washington at Lincoln Financial Field last season. For a 36-year-old left tackle, that recovery is not an easy one.

But Peters is making sure not to overcompensate that injury and hurt himself somewhere else. He's continuing to work on his base and his leg strength and his ability to anchor. In the meantime, something more significant on the injury front happened a couple of weeks ago when Peters suffered a biceps injury in the win over the Giants. Peters left that game but has not missed work since.

And he'll be in the starting lineup on Sunday against a very good Jacksonville front.

"They're fast, a lot of games, a lot of twists and stunts," Peters said. "A lot of movement."

In other words, Peters is going to have his hands full, just like he does every week.

"That's the nature of the job and I'm up to the challenge," he said. "I'm not going to let the team down. I'm going to be out there doing my best. This is a big game for us. We need this win."
