DETROIT — Every one of his teammates had left the visiting locker room at Ford Field, and Lane Johnson was still there, still slowly getting dressed.

It almost seemed like he was savoring every moment he could in an NFL locker room because he knew he’s most likely about to take a long break from them.

Johnson, who appealed his 10-game suspension for a banned substance to the NFL on Tuesday, spoke publicly about his appeal hearing for the first time after Sunday's Eagles-Lions game.

He said he expects to hear something from the league on either Wednesday or Thursday.

The NFL arbiter can keep the 10-game suspension or fully rescind it.

“It was eight hours of bickering back and forth and discussing league policy,” Johnson said. “It just felt good going in there and taking it head on. It was mainly just a conversation on the policy (the NFL has) in place. It didn’t have to do with any substances, mainly just changing the testing procedures.”

Johnson, who was suspended for four games in 2014, was vague about the specific nature of his appeal and what part of the league’s testing procedures he was challenging.

He has said he believes he was suspended for taking a supplement that is allowed by the NFL but was tainted by the manufacturer to include peptides, which are banned and were not listed on the label.

Johnson said he did little talking during the appeal, leaving that to his attorneys.

He said he felt like he left the hearing feeling he and his representatives had clearly stated his case.

“We put it all on the floor,” he said after the Eagles’ 24-23 loss to the Lions (see Instant Replay). “We didn’t have anything to hide. I feel like we did all we could. There wasn’t a stone left unturned.

“Man, the thing was, just face it head on. We weren’t going to be intimidated by the NFL.”

Johnson has remained the Eagles’ starting right tackle since word of the likely suspension leaked out nearly two months ago.

If Johnson learns this week that he’s out for 10 weeks, he won't be back until the Eagles face the Giants on Dec. 22 at the Linc.

Johnson will not be allowed inside the NovaCare Complex if he is suspended. He said he plans to stay in Philadelphia and train on his own during the 2½ months he is likely to miss.

“Stay in shape and hopefully the team is good enough to stay in playoff contention,” he said. “Come back and I’ll be fresh and we can make a run for it. That’s the best-case scenario. We’ll see what happens.”

If this was Johnson’s final game until Christmas week, it was an agonizing one to lose.

“It’s tough, man,” he said. “I thought we should have won that game.
