The hearing for Lane Johnson's appeal of a 10-game suspension for using a banned performance-enhancing substance was held in New York City on Tuesday and a decision from an arbitrator is unlikely to be rendered before the Eagles travel to Detroit to face the Lions on Sunday, said Johnson's attorney, Steve Zashin.
"There are a number of issues relative to Lane's appeal," Zashin said in a statement. "Many of those issues strike at the heart of substantive player protections. We await the decision of the arbitrator. In the meantime, Lane will prepare and play as scheduled."
Johnson declined to comment.
Zashin declined to give a time line for the decision, although past appeals typically take seven to 10 days. If Johnson's appeal is denied next week he will likely begin his suspension immediately and won't be available to return until Dec. 19 for the final two games of the season.
The 26-year-old would be required to stay away from team facilities in the interim.
The Eagles practiced with Johnson at right tackle on Monday. The team had prepared for the possibility of his suspension during the preseason by moving left guard Allen Barbre to right tackle and inserting either Stefen Wisniewski or rookie Isaac Seumalo at left guard.
Coach Doug Pederson recently said that it would likely be Wisniewski at left guard, although an ESPN report on Tuesday said that rookie Halapoulivaati Vaitai could be an option at right tackle.
Johnson is facing his second suspension for using a banned substance. He missed the first four games of the 2014 season for using Adderall. Johnson said in August that he tested positive for peptides after he took an amino acid supplement. He claimed that the supplement was cleared by the Aegis smartphone app provided by the NFL Players Association.
The league and the players union, though, have never endorsed the use of supplements and have said that it is ultimately the player's responsibility for what he ingests.
It is unlikely that the arbitrator can lessen Johnson's suspension. A reduction would have had to occur during discussions between the league and the union before the appeal.
