ORCHARD PARK, N.Y. -- Bills safety Aaron Williams was too excited to return to practice for the first time in nearly a month to worry about the potential long-term effects his latest head injury might have on his career.Honestly, it probably does have an effect on the future, Williams said at his locker Tuesday.But am I thinking about that? No. I cant think about that because if I think about it, its going to happen, he added. I love this game to the bottom of my heart, and would do anything to keep playing.The sixth-year player acknowledged he needs to play smarter to reduce the risk of head injuries.Williams was cleared to practice, and coach Rex Ryan said the starter is ready to go for Buffalos season opener at Baltimore on Sunday.Williams has been out since sustaining a concussion on Aug. 11, when he collided with receiver Dez Lewis during a team drill at training camp.The injury came on the heels of Williams having season-ending neck surgery in which doctors shaved two disks to alleviate nerve damage. He was hurt while diving headfirst in an attempt to tackle Patriots receiver Julian Edelman in Week 2.The collision with Lewis happened when Williams was trying to break up a pass over the middle.Williams called it a freak accident, and said his first concern was whether he re-injured his neck.I couldnt really tell you what I was thinking or what was going on in my mind because the whole time my head was ringing, Williams said. I was trying to make sure that my neck was actually good. I was more concerned about my neck than I was my head.Williams previously acknowledged he would not have returned to play this season if doctors informed him there was any risk of aggravating the neck injury.He is also taking steps to alter his tackling technique so his head and neck are less exposed. Williams did that by leaning on the advice of former NFL star safety and first-year Bills defensive backs assistant Ed Reed.Williams said Reed provided numerous pointers while going over practice and game film.He said, `You like to hit too many times for unnecessary reasons, Williams said. But I never knew that because I only knew one way to play, and that was to stop the person who had the ball no matter what the repercussions are.That doesnt mean Williams intends to play cautiously.I wont play, I guess, conservative, if you want to put it, Williams said. I only know one speed to play and thats full speed. And I told coach Im ready to go.Right tackle Seantrel Henderson returned to practice after missing last week for an undisclosed reason. Without going into detail, Henderson said his absence was related to having offseason surgery on his intestines to relieve the effects of Crohns disease.Henderson was out since making his preseason debut in playing 41 of 77 snaps in a 21-16 loss at Washington on Aug. 26.Henderson said hes feeling normal and everything checked out fine.Game notesRB LeSean McCoy practiced after being excused for the start of the session for personal reasons. ...

Busch will start ninth, Edwards 10th, Logano 13th and Johnson 14th. Johnson would match Dale Earnhardt Sr. and Richard Petty for the NASCAR record with his seventh career Cup championship.I dont think any of us want to start that far back, Edwards said.But they are bunched close enough that one TV camera can probably catch them all as they head into the first turn on the 1.5-mile track. Busch started third in the finale last season, won the race and his first career Cup title.The foursome likely wont lag behind the front of the field for long.This is a place you can pass, Logano said.The highest-finishing driver among the four is the 2016 champion. Under the revamped Chase format, the Homestead winner the last two years won the championship.Kevin Harvick and Brad Keselowski, eliminated from title contention in earlier rounds of NASCARs playoffs, played spoiler and swept the front row.I think weve been the two best cars all year, Keselowski said.Ryan Newman, Denny Hamlin, Chase Elliott, Martin Truex Jr., Matt Kenseth and Ryan Blaney all wiill start ahead of the championship drivers.ddddddddddddThe drivers out of the championship picture traditionally part to let the contenders race each other hard in the meat of the race.You get a little more respect from those guys, Busch said.Amid a heap of tributes, Tony Stewart starts 11th in the final race of his NASCAR career. Stewart is trying to race to his 50th career Cup victory and end a triumphant career in victory lane.There hasnt been any part of my career that I didnt enjoy, Stewart said. There are things about everything that Ive done that Ive liked more than others and disliked more than others. But as a whole, Ive enjoyed everything Ive done and the road that Ive taken to get here.Edwards and Busch are each vying to win a second straight championship for Joe Gibbs Racing. Johnson could bring a 12th title to Hendrick Motorsports. Logano wants to reward Roger Penskes 50th season in racing with another championship.Asked what keeps him going after all these years, Penske quipped, Trying to beat these guys.Harvick, the 2014 Homestead winner and Cup champion, won his second pole of the season. The Stewart-Haas Racing driver could also deliver a victory celebration for Stewart.Johnson was antsy to chase history.Qualifying isnt my strong suit, Im much better at racing, he said. So lets line them up and go racing. ' ' '
