Buffalo Bills offensive tackle Seantrel Henderson was suspended for the first four games of the 2016 NFL regular season Wednesday for violating the league's substance-abuse policy.
ESPN's Adam Schefter was the first to report the news and added that Henderson is appealing. Schefter also reported Henderson's positive test was due to a substance used to treat Crohn's disease.
According to NFL Network's Ian Rapoport, Henderson tested positive for marijuana, which can be used to treat the pain associated with Crohn's disease.
Henderson was diagnosed with the digestive condition last December, and it caused him to miss the final five games of the 2015 season.
