-- Pittsburgh Steelers receiver Martavis Bryant is facing a four-game suspension, pending an appeal, for violating the NFL's substance abuse policy, league sources told ESPN's Adam Schefter on Thursday.
Bryant, a fourth-round selection in the 2014 draft out of Clemson, caught 26 passes for 549 yards and eight touchdowns during his rookie season with the Steelers.
Last year, Bryant was only the second rookie receiver since 1995 to gain more than 20 yards per reception (minimum 25 catches). Kenny Stills also accomplished the feat in 2013 with the Saints.
Bryant underwent a minor procedure earlier in training camp for an elbow infection and missed a few days of practice.
The Steelers already will be without starting running back Le'Veon Bell for the season opener against the New England Patriots on Sept. 10, when he will be serving the first game of his two-game ban stemming from an August 2014 arrest on DUI and marijuana possession charges.
