ORCHARD PARK, N.Y. (AP) -- Buffalo Bills right tackle Seantrel Henderson has been suspended by the NFL for the first four games of the season for violating the league's substance abuse policy.

The Bills announced the suspension Friday, and Henderson's agent, Brian Fettner, told The Associated Press that his client has elected to not appeal the ruling.

Fettner said Henderson tested positive for marijuana, which he was using for medicinal purposes to relieve the effects of Crohn's disease. Henderson was diagnosed with the inflammatory bowel disease late last year, and had two operations on his intestines
this past offseason.

He rejoined the team in late May and was cleared for practice last month.

Henderson declined to comment following practice on Friday.
