Seantrel Henderson appeared to be on the cusp of earning his starting job back at right tackle just a week ago.
Now, however, the Buffalo Bills' offensive lineman faces a very uncertain NFL future.
Henderson was suspended for 10 games by the league Tuesday for a second violation of the substance-abuse policy. The Buffalo News reported last week that a second suspension was possible. Henderson previously sat out the first four games of this season after testing positive for marijuana.
"The league has notified us of the suspension and we are moving forward with our preparations to play the Oakland Raiders this Sunday," the Bills said in a statement.
Henderson maintains that his marijuana use is for medicinal purposes as it relates to his battle with Crohn's disease. A league source told The News that Henderson could pursue legal action against the NFL if he were to be suspended a second time.
