Ajayi joined the Eagles via trade in October and went on to win a Super Bowl with the squad in February. He enters the 2018 season as the team's lead back, but is expected to share passing down work.
Foles, the Super Bowl MVP, will start for the Eagles on Thursday when they take on the Atlanta Falcons in the first game of the NFL season. Wentz is still recovering from knee surgery and has yet to be medically cleared for contact.
"We have both of them out there at practice," Ajayi told UPI. "I don't even think Carson has been cleared by the doctors anyway yet ... It doesn't really matter what he wants. As soon as he can do that, then he'll get out there."
Ajayi said he will go with whoever is under center and everyone is doing their respective jobs. But the Eagles obviously have a lot of confidence in Foles.
"I respect Nick a lot," Ajayi said. "He has done a lot for Philadelphia and for our team and I appreciate him being here again for another year and having him as our quarterback."
Eagles coach Doug Pederson told reporters Tuesday that Wentz is "probably disappointed" that he can't be out with the team for Week 1.
"Carson is in a great spot," Pederson said. "He's in a great spot right now. He's supportive. He understands. He knows exactly where he's at. He works every single day to get back on the field. That's all I can ask for."
Wentz isn't the only bruised Eagles star entering the team's title-defending campaign.
Ajayi's Injury and 2018 Role
Ajayi returned to practice on Monday after sitting out for two weeks with a foot injury. But the 2016 Pro Bowl selection said he is working hard to be in good enough shape to suit up against the Falcons.
"I'm just listening to our trainers and our coaches and doing whatever I need to do to be able to play," Ajayi said. "So hopefully by game time ill be good to go."
With the departure of LeGarrette Blount, the lead role in the Eagles' backfield has Ajayi's name on it. He was touted as a "bell-cow" when he played for the Miami Dolphins, but is willing to do whatever is asked by his coaches in Philadelphia.
Ajayi had just 408 yards and a score on 70 carries in seven games for the Eagles last season after coming over from the Dolphins.
"Well I look at myself as a guy that can do it all when called upon," Ajayi said. "Whatever the coaches want, that's what I'm going to do."
The four-year veteran is coming off of his first Super Bowl victory, but is trying to enter the season with a normal mindset.
"Obviously it's special, but for me I'm looking at it as another season, not as coming in as Super Bowl champs," Ajayi said. "It's just another year. Everyone is on the same level right now."
Looking for a Fan
