ORCHARD PARK, N.Y. -- Having spent the past four months showing hes capable of keeping the effects of Crohns disease in check, Bills offensive tackle Seantrel Henderson faces yet another hurdle in attempting to resume his career.Henderson is appealing the NFLs four-game suspension for violating the leagues substance abuse policy after testing positive for marijuana, a person with direct knowledge of the situation confirmed to The Associated Press on Wednesday. The person spoke on the condition of anonymity because the suspension is being appealed and the NFL has not announced its ruling.The person said Hendersons appeal is based on him using marijuana for medicinal purposes to relieve the effects of Crohns disease. Henderson was diagnosed with the inflammatory bowel disease late last year, and has since had two operations on his intestines. The first operation occurred in January, when doctors removed a section of diseased tissue. In April, he had surgery to have his intestine reattached.Several studies have found marijuana can be an effective treatment for people diagnosed with Crohns disease.In New York, the states medical marijuana program specifically lists patients diagnosed with inflammatory bowel disease as being potentially eligible to obtain medical marijuana.ESPN.com first reported Henderson was facing a suspension.NFL spokesman Brian McCarthy said the league has no comment.Coach Rex Ryan would only refer to questions regarding Henderson as a league disciplinary issue, and directed questions to the NFL.Ryan said the team and league provides its players several programs in dealing with substance abuse issues.Guys have to be accountable and understand that its not tolerated, Ryan added.

One day Im in surgery, the next day the doctors saying I might not be able to play no more.Henderson has been a two-year starter at right tackle since being selected by Buffalo in the seventh round of the 2014 draft. His stock in the draft plummeted after Henderson openly acknowledged he had a history of marijuana use. He tested positive for the drug at the NFL combine in 2014 and he said positive tests led to him being suspended several times at the University of Miami.The news of Hendersons possible suspension caught his teammates by surprise.Really?

Andretti drivers have won four of the last eight IndyCar races at Milwaukee, and Michael Andrettis marketing group is in its second year promoting the event. So when his son, Marco, jumped to P1 in Fridays qualifying session, followed by all three of his teammates, he could chuckle that perhaps something was awry. "We get extra horsepower here," Michael Andretti joked. In the end, Will Power of Penske Racing prevented an Andretti sweep by wedging himself in the middle of the four Andretti cars. When the field goes green Saturday, it will be Marco Andretti and James Hinchcliffe starting on the front row, followed by Power and then Andretti drivers Ryan Hunter-Reay, the defending race winner, and E.J. Viso. Asked what was up with the Andretti domination, Hinchcliffe had an answer far more entertaining than a claim of extra horsepower. "Pixie dust," Hinchcliffe said. "We were cleaning out the attic at the shop and came upon this little bag, and we spread the dust over all the cars." All jokes aside, its shaping up to be a race for an Andretti driver to lose in Saturdays 250-mile event. Marco Andretti won the pole with a two-lap average speed of 170.515 mph around the mile oval. Its his second career at Milwaukee, and third overall, and he beat Hinchcliffes average of 170.418 for a front row sweep for the Andretti cars. "Thats as good as I could have done," said Andretti, who scoured the qualifying order after his lap. "Im dying to see who is out there who can beat me." Power was third at 170.212, followed by Hunter-Reay and Viso. Sebastian Saavedra was sixth and Tony Kanaan was seventh as Chevrolet drivers swept the top seven spots. Josef Newgarden was the highest qualifying Honda at eighth.dddddddddddd Helio Castroneves, last weeks winner at Texas, qualified 18th. His car failed post-race inspection Saturday night and IndyCar this week fined Penske Racing $35,000 and docked Roger Penske 15 owner points. But Castroneves maintained his lead in the IndyCar Series standings, which is 22 points over Marco Andretti. Marco Andretti, though, has his eye on the winners circle Saturday. Hes finished inside the top seven in seven of the eight IndyCar races this year and is eager to grab his first victory since 2011. "Man, I am so hungry to get the monkey off my back because once I do, I think they (wins) are going to steamroll from there," Andretti said. "Were knocking on the door and thats all weve got to do. Hopefully it will come through." And the pressure is on for Andretti to do it this weekend at Milwaukee as a Fathers Day gift to Michael. "It would be huge, and I told him hopefully this is only part of his Fathers Day gift," Marco said. "We have the car to do it, we have four great shots. I also have to credit Andretti Autosport as a whole, four out of the top five is pretty awesome." Especially considering how far off Hinchcliffe was in both practice sessions Friday. He smacked the wall in Turn 2 in the first session, damaging his car, and was far off of his teammates pace. "Change after change didnt seem to make it any better and it was tough," Hinchcliffe said. "We were scratching our heads wondering what we should do, and our teammates were first, second and fourth, just making us look stupid. We went through the whole car and my head was in the wrong place. "But everybody did a good job. The team did its job in getting the car sorted, and I pulled my head out to forget about practice and here we are." ' ' '
