Julian Edelman's appeal of his four-game suspension for violating the league's performance enhancing drug policy was denied Tuesday, according to a report from ESPN's Adam Schefter.

Edelman's representatives focused on two key issues during his appeal, which was heard on June 25.

One issue, the substance that Edelman tested positive for, as it wasn't recognized by the league's drug testers.

The other involved the mishandling of documentation and the delivery of Edelman's results.

It was determined during the course of the investigation that mistakes were made by the NFL in the handling of Edelman's results, something his representatives had hoped would lead to a successful appeal of his four-game ban.

The 32-year-old wide receiver missed the entire 2017 season after suffering an ACL tear in the preseason.

He could try to appeal his case in federal court.
