Martavis Bryant faces year-long suspension

— -- Pittsburgh Steelers wide receiver Martavis Bryant is facing a year-long suspension from the NFL, his agent confirmed to ESPN's Jeremy Fowler.

The suspension is related to NFL drug testing, a source told Fowler. Bryant's agent confirmed Saturday that the talented receiver plans to appeal the suspension.

DKPittsburghSports.com was first to report the potential suspension Saturday morning.

Bryant served a four-game suspension last season for violating the league's substance abuse policy. He returned to have a productive season for the Steelers, hauling in 50 receptions for 765 yards and six touchdowns in 11 games.

Upon returning from his suspension last October, Bryant thanked the Steelers for their support and said he "learned" from his mistake and wanted to "move on from it and put it in the past." Bryant also said he had spent time with former NBA player and coach John Lucas, who operates a substance abuse recovery facility in Texas.
