Lane Johnson, who signed a five-year, $52.25 million contract extension in February, is reportedly facing a 10-game suspension for violating the NFL PED policy.

Fox Sports reported that Johnson said he took an approved amino acid but tested positive for a banned peptide, and he is appealing the suspension, which was first reported via Twitter by Wildfire Radio and confirmed by NFL Network.

"We are aware that a member of the media has started a rumor that Lane Johnson will be suspended for a PED violation," said Johnson's agent, Ken Sarnoff, in a statement released to ESPN on Tuesday. "Lane has not been suspended and any report to the contrary is false. None the less we will not comment on my client's protected health information."
