ORCHARD PARK- Buffalo Bills offensive lineman Seantrel Henderson faces a four-game suspension for violating the NFL's substance abuse policy, according to multiple reports.
Per ESPN's Adam Schefter, the suspension is related to a treatment Henderson had for Crohn's Disease.
NFL Network's Ian Rapoport reports marijuana can be used to help deal with the pain of Crohn's.
Henderson, who has been battling Crohn's since 2015, is appealing the suspension.
As a rookie in 2014, Henderson started all 16 games at right tackle. He missed the final three games of 2015 after he was diagnosed with the disease.
Henderson was out practicing with the team during the appeal.
