ORCHARD PARK, N.Y. -- The Buffalo Bills have secured at least one half of their starting safety tandem after signing Aaron Williams to a four-year, $26 million contract extension Wednesday. A person with knowledge of the contract said Williams is guaranteed $14.625 million. The person spoke on condition of anonymity because the terms were not released by the Bills. The extension locks up Williams through 2018, and comes at a time when the Bills risk losing three-time Pro Bowl safety Jairus Byrd, who is preparing to test free agency next week. "I told them I accept the role of leading this defence to where it used to be," Williams said. "Im just blessed that they gave me that opportunity, and they trusted me to be here long-term to get this team back to where it started." Williams, Buffalos second-round pick in the 2011 draft, was entering the final year of his contract. He was rewarded with the extension after successfully making the switch from cornerback to safety last season. In 14 games last year, Williams had a career-best 82 tackles and tied Byrd for the team lead with four interceptions. Overall, he has five interceptions and two forced fumbles in 34 career games. "Aaron is the type of young, core player we targeted early in the process to retain for years to come," general manager Doug Whaley said in a released statement. "We expect Aaron to continue to grow into a key contributor for the Bills organization." The question is whether Williams will continue to develop alongside Byrd. This week, the Bills decided against applying the franchise tag for a second consecutive year to retain Byrds rights, opening the door for the fifth-year player to test free agency on March 11. Williams is hoping the Bills can still reach a deal to re-sign Byrd, because the two established a solid on-field rapport last season. "If Jairus does come back, that would be the greatest thing ever, because our chemistry is unbelievable," Williams said. "If he doesnt come back, good luck to him. Were always going to be best friends. ... Well just have to move on and find another piece to try to replace his role." The Bills defence is undergoing another off-season change, with Jim Schwartz taking over as co-ordinator after Mike Pettine left to become the Cleveland Browns head coach. Schwartz has a similar aggressive defensive coaching philosophy, which is expected to ease the transition. "I feel real confident that nothing major is going to change," Williams said. "There might be a few things here and there, but I think team-wise, once we get all the pieces together we will be fine." The Bills also announced free-agent linebacker Jameel McClain had arrived in Buffalo to meet with team. Listed at 6-foot-1 and 245 pounds, McLain spent the past six seasons with the Baltimore Ravens before being released by the team last week. Discount Yeezy .

Dragic was a game-time decision because of a sore right ankle that had kept him out of Wednesdays loss at Utah, but played all but the last 10 seconds of the second half in the first 40-point game for a Phoenix player since Amare Stoudemires 44 on March 19, 2010.MANCHESTER, England - Manchester United relied on a fortunate winning goal from Juan Mata and a breathtaking double save from David de Gea in injury time to beat Stoke 2-1 and secure a fourth straight Premier League victory on Tuesday.Comfortable but never convincing at Old Trafford, United ended up scrambling to the three points that kept the team in the top four and maintained its revival under new manager Louis van Gaal.Matas winner in the 59th minute had a slice of fortune about it, with the Spain playmakers inswinging free kick from the right curling over the heads of a number of players in the box and bouncing into the far corner.However, it needed two superb saves from De Gea and a goal-line clearance from Ashley Young — all in the final two minutes of injury time — to prevent Stoke from checking Uniteds momentum.I am not happy with the performance, Van Gaal said. Maybe we forced the luck and that is also because of the fighting spirit.Without the injured pair of Wayne Rooney and Angel Di Maria, United lacked creativity and took a 21st-minute lead through a direct route when Marouane Fellaini scored a towering, far-post header.Steven Nzonzi equalized in the 39th for Stoke with a powerful shot from the edge of the area and failed to genuinely test United until a frantic, final few minutes.The episodes at the end were unbelievable, said Stoke manager Mark Hughes, who spent 13 years at United as a player across two spells.United has beeen looking to restore the fear factor at Old Trafford — but its makeshift team was far from intimidating without Rooney and Di Maria, and a defence containing wingers Young and Antonio Valencia as full backs.ddddddddddddIn the end, two high balls into the box — crosses that Stokes physically imposing teams down the years were masters at dealing with — were the downfall of the hard-working but limited visitors.Fellaini nipped in front of left back Erik Pieters to meet a hanging cross to the far post by Ander Herrera with a downward header into the centre of the goal. Stoke should have been behind by then, with Herrera blasting a shot over the bar after Robin van Persie had intercepted a weak clearance by goalkeeper Asmir Begovic.Nzonzi scored with Stokes only shot on goal in the first half but United restored its lead just before the hour mark when Mata swung in a cross that narrowly eluded leaping United defender Marcos Rojo, who initially claimed the goal, and dropped into the far corner.Fit-again Colombia striker Radamel Falcao came on for the final 12 minutes for United to replace 19-year-old James Wilson, who came in for Rooney.But it was Stoke which finished the stronger, with Mame Biram Diouf seeing a header brilliantly parried out by De Gea and then having his goalbound shot cleared off the line by Young.Im happy with the result, Van Gaal said, tomorrow we have a Christmas party and its important we can enjoy that.
