UPDATE: Now Johnson is confirming he's facing a suspension. Via Jay Glazer on Twitter:
Just heard from Lane Johnson, says he took an amino acid that was approved but tested positive for peptide. Fighting it as well as company. You're responsible for what goes in your body but he insists it was approved. Waiting on B sample

Lane Johnson just responded to text message and said that "all was good," and denied report he's been suspended for 10 games for PED use.— Jeff McLane (@Jeff_McLane) August 9, 2016
The report of Johnson's potential suspension emerged earlier on Tuesday afternoon. Darren DeGaetano first reported the story before Howard Eskin and Ian Rapoport later followed up with confirmation. Rapoport also noted Johnson is appealing the suspension.
Losing Johnson would obviously be a major blow for the Eagles. Philadelphia could potentially be missing their starting right tackle for more than half of the 2016 NFL season. The Eagles' depth at tackle is already questionable, especially given the shaky health status of 35-year-old left tackle Jason Peters.
