According to ESPN's Adam Schefter, Martavis Bryant is facing a four-game suspension for violating the NFL's Substance Abuse Policy.
Bryant is entering his second year in the NFL, and while Markus Wheaton has been listed ahead of him on the depth chart, Bryant's been the better target in fantasy football. He ranked second in the league behind only Kenny Stills in per-target Reception NEP last year, and was expecting a larger role in the Steelers' offense in 2015. Wheaton's stock is up, while Bryant's is obviously down.
