PITTSFORD, N.Y. -- Out of shape and preparing to serve a four-game suspension, Buffalo Bills running back Karlos Williams is apologetic when bluntly assessing the fix hes put himself in.Im very disappointed in myself. I put the organization, my teammates, my family in a very bad situation, he said, upon reporting for the start of training camp this weekend.I only can learn from my mistakes this offseason and get ready to get back in shape, get ready to play football, and only can move forward.Theres no point looking back on an offseason that went from bad to worse for Williams, who made a significant contribution to Buffalos NFL-leading rushing attack as a rookie last season.You cant change what happened, he said. All you can do is work, work, work and get ready to play football.He has plenty of time to get into shape. Aside from the suspension, Williams isnt cleared for practice and instead is taking part in conditioning drills while opening camp on the active/non-football illness list.The trouble began in June, when he raised concerns by showing up overweight for a three-day mandatory minicamp. Williams blamed the added bulk on being empathetic to his fiance and not wanting her to snack alone during her pregnancy.Though it was never made clear how overweight Williams was, coach Rex Ryan joked the player might be a candidate for Lap-Band surgery.No one was laughing a few weeks later, when the NFL announced Williams four-game suspension for violating the leagues substance abuse policy.The 23-year-old Williams chalked it up to being a young kid, and just making bad decisions, not thinking things through.His stumbles happened as quickly as his ascension last year.Williams was considered a project when Buffalo drafted him in the fifth round out of Florida State. At 6-foot-1 and 230 pounds, he had the combination of size and speed to play running back. What he lacked was experience at the position after making the switch from safety during the 2013 season.Williams immediately dispelled any questions by becoming the second NFL player to score touchdowns in his first six games -- and at a time when starter LeSean McCoy was hampered by a hamstring injury.With a powerful, straight-ahead running style, Williams scored three TDs rushing and another receiving in his first four games before missing three with a concussion.He then returned to score two more rushing and another receiving in his next two games, and finished with 517 yards rushing, 96 receiving and nine touchdowns (seven rushing and two receiving) in 11 games.The question now is what role Williams will have once hes eligible to return in Week 5.General manager Doug Whaley provided no guarantees.Hes a young guy and hes got to understand that everybody that comes into this building or into camp is competing for playing time and cap space, Whaley said. Hes behind the 8-ball right now. And I think hes more disappointed than we are.The Bills have depth at running back, starting with Mike Gillislee, who played a complementary role in closing last season. Buffalo also re-signed Boom Herron and added James Wilder Jr., the son of former Buccaneers fullback James Wilder.Then theres fifth-round pick Jonathan Williams, who faces potential discipline after being arrested in Arkansas on a misdemeanor charge of driving while intoxicated two weeks ago.Karlos Williams first concern is getting back on the field.I can control me, and all I can control right now is being in shape, Williams said. Its all about showing people, showing my family, showing my friends, the ownership, my coaches, my teammates and definitely earning my teammates trust back.---AP NFL websites: http://pro32.ap.org and http://twitter.com/AP-NFLDiscount Yeezy 350 V2 .Y. -- Syracuse has turned up the defence at the right time all season, and when High Point threatened to pull off a monumental upset the second-ranked Orange did what they do best with their quick hands and savvy play.

The recently retired Stern was elected Friday to the Naismith Memorial Basketball Hall of Fame and will be enshrined with the class of 2014 on Aug. CHARLOTTE, N.C. -- Panthers coach Ron Rivera wants Cam Newton to receive the same protection on helmet-to-helmet hits as other quarterbacks get in the NFL.Rivera said because of the 6-foot-5, 245-pound Newtons size and the Panthers style of play, Newton often doesnt draw the flags on hard hits that smaller QBs do.Newton was on the receiving end of four helmet-to-helmet hits in Thursday nights physical 21-20 loss to Denver, but the Broncos were only penalized once.I think there is a little bit of prejudice to that, Rivera said of the lack of penalties. Its kind of like Shaquille ONeal. Hes a big physical basketball player and he goes to set a pick and they fall down and they call a foul on him. Then he goes to shoot a layup and gets hacked and hammered and they dont call it.Rivera even went as far as to say the leagues reigning MVP should receive some preferential treatment.The coach would like to see Newton, now in his sixth season, get some veteran favoritism from the leagues officials.Newton was tested four times for a concussion -- after the game in the locker room, on the bus, on the flight home and Friday morning at the stadium -- and all proved to be negative. He was never tested during the game.Newton is expected to practice when the Panthers return to the field on Wednesday, the coach said.Rivera said he will send video of some of the hits to the league.Some of them you would like to see them throw the flags, Rivera said without identifying which hits.The NFL doesnt disagree with Rivera. A person with knowledge of the situation told The Associated Press that league officials say linebacker Brandon Marshall should have been flagged for a second half hit on Newton.The person said Dean Blandino, the leagues senior vice president of officiating, and his staff reviewed the play and determined on Friday that Marshall shouldve been flagged for delivering a hit to Newtons head after the quarterback had released the football. The person spoke to the AP on condition of anonymity because the NFL did not publicly comment on the details of its review.The NFL wont hand out any potential fines until next week after they review all Week 1 games.There were a couple of helmet-to-helmet hits on Newton by last years Super Bowl MVP Von Miller and defensive end Jared Crick. Millers facemask-to-facemask hit occurred while Newton was being sacked by DeMMarcus Ware.ddddddddddddThe biggest hit on Newton, however, was delivered by safety Darian Stewart on Carolinas final possession, leaving the QB motionless on the ground for several seconds. Newton stayed in and led the Panthers into field goal range, although Graham Gano missed a 50-yard attempt that would have given Carolina the lead.Stewart said after the game he felt like he led with his shoulder, not his head.The NFL released a statement Friday saying medical officials determined Newton didnt need to leave the game due to injury. It said there was communication between medical personnel on the Carolina sideline, including the unaffiliated neurotrauma consultant, and the two independent certified athletic trainer spotters in the booth.The release also stated that during stoppage in action the play was reviewed and medical officials determined there were no indications of a concussion that would require further evaluation and the removal of the player from the game.Rivera didnt see a need to sit Newton after the hit.Im not going to question the doctors, OK? There is a protocol, Rivera said.The NFLPA said it is reviewing whether Newton should have been tested after the hit.Broncos coach Gary Kubiak said he didnt think there was that much contact with Newtons head during the game.I saw two plays where he left the pocket where there were big collisions, Kubiak said. There were a lot of big collisions in that game. I think we were playing hard. They were playing hard. They knocked the heck out of us, too, you know.Kubiak also doesnt feel his players were being dirty.Rivera knows officials have a difficult job to do, especially when it comes to a player like Newton who runs a lot.I think his style of play is different as far as quarterbacks are concerned, Rivera said. ... Its so hard to tell whether he is running or going to throw. So that makes it tough.Kubiak agreed.Hes the top player in football and theyre designed runs for him, Kubiak said. Youd better tackle him like a back, youd better treat him that way or youre going to have a long night as a defensive football team.---AP NFL website: www.pro32.ap.org and www.twitter.com/AP-NFL---AP Pro Football Writer Arnie Stapleton in Denver contributed to this report.
