Reports: Patriots WR Edelman facing 4-game PED ban

New England Patriots wide receiver Julian Edelman is facing a four-game suspension for violating the NFL's policy on performance-enhancing substances, according to multiple reports Thursday.

The suspension is reportedly under appeal. Edelman has never tested positive before despite "hundreds of tests," according to ESPN.

Edelman missed all of last season after tearing the anterior cruciate ligament in his right knee during a preseason contest. The 32-year-old has been on the field during the Patriots' mandatory minicamp this week after previously attending voluntary OTAs.

If suspended, Edelman would forfeit roughly $470,588 of his $2 million base salary this season. He would miss contests against the Houston Texans, Jacksonville Jaguars, Detroit Lions and Miami Dolphins before being eligible to rejoin the team on Oct. 1.

Edelman has 425 catches for 4,540 yards and 24 touchdowns in his nine NFL seasons.
