KANSAS CITY, Mo. -- Derrick Johnson knew his season was over the moment he hit the frozen turf of Arrowhead Stadium, the Chiefs veteran linebacker ripping off his helmet in frustration.It became official when he went to the sideline and found he had torn his Achilles.The injury only briefly deflated Kansas City on Thursday night, though. The Chiefs defense seemed to rally around their fallen leader in the second half, shutting down the Oakland Raiders to preserve a 21-13 victory that gave them control of the AFC West.Hes a guy I respect so much, and just to see the look on his face when it happened, it looked serious, Chiefs quarterback Alex Smith said. Theres not a guy in the locker room that doesnt look up to D.J., so yeah, in a big game like that, hats off to our defense for responding.Something like that can hurt you big-time and our guys didnt miss a beat.Kansas City had just taken a 21-3 lead in their AFC West showdown when Johnson fell to the turf away from the play. The look of frustration on his face was evident as the training staff and coach Andy Reid ran onto the field, and as his left shoe was removed and the examinations began.Johnson was helped off the field without putting any weight on his foot, and he spent the rest of the half sitting on one the heated benches in somber silence.I felt a little bit of a letdown when it happened, but Justin (Houston) and Eric (Berry) reeled everyone in and got after it. The last thing D.J. would want is a letdown.Johnson ruptured his right Achilles in similar fashion two years ago, and the Chiefs proceeded to lose the game. But this time, they managed to squeak out a crucial win for their playoff hopes.We made adjustments but we got it done, fellow linebacker Dee Ford said. My heart goes out to him. Its hard. But were going to keep moving. Thats life. But were going to miss him.The 34-year-old Johnson, already the Chiefs career tackles leader, had been having another stellar season. He came into the game with 89 tackles, a sack and an interception that he returned for a score to highlight the first year of a $21 million, three-year deal that he signed in March.Kansas City was already without middle linebacker Josh Mauga, who had season-ending surgery to his hip in training camp, and Justin March-Lillard, who had surgery on a broken hand in October.Reid indicated its possible that one of them could return before the playoffs.Thats part of the equation, Reid said. Well discuss that tomorrow, but thats part of the equation. We have the flexibility to do that.The Chiefs also lost defensive tackle Rakeem Nunez-Roches to back spasms in the first half, while Oakland was missing three starters at kickoff after offensive lineman Kelechi Osemele was scratched with an illness that ultimately landed him in the hospital.Safety Karl Joseph had already been ruled out with a toe injury and defensive tackle Stacy McGee was out with an ankle injury.I saw him prior to the game and there was no way I could ask him to try, Del Rio said of Osemele, who has also been dealing with a knee injury. Not trying to get into specifics, (but) it was significant enough we wanted to make sure we got him to the proper care.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFLFake Jerseys Outlet .

MIAMI -- Grateful for great blocking that paved the way to his first career 200-yard game, Miami Dolphins running back Jay Ajayi offered to treat his offensive line to dinner.The response: Well take a rain check.I just wanted to show some appreciation to those guys, Ajayi said. They told me, `Its not a one-hit thing, and, `Lets do it again. And lo and behold, we did it again.Ajayi tied an NFL record by topping 200 yards rushing in a second consecutive game, and this week he became the first running back to win offensive player of the week in back-to-back weeks since LaDainian Tomlinson a decade ago.Even then there was little celebrating, because Ajayi has the Dolphins thinking big.By carrying Miami (3-4) to victories over Pittsburgh and Buffalo, he saved the season and raised hopes the franchises eight-year postseason drought might soon end.When were in the playoff hunt, I can celebrate, tackle Branden Albert said. Until then Im not celebrating. He doesnt need to take us out to dinner. Im just happy hes doing good and were doing good as a team.The Dolphins have reason to believe their recent success can be sustained.Following a wave of injuries and illness in an offensive line that includes four former first-round draft picks, the group was finally intact for the past two games, allowing Miami to physically dominate teams coached by Mike Tomlin and Rex Ryan.In other words, the wins were no fluke.This team can be special if we keep doing the things were doing, center Mike Pouncey said.Mostly what theyre doing is handing the ball to Ajayi, a second-year pro from England who has more than doubled his career rushing total in the past fortnight.At 6-foot and 229 pounds, Ajayi mixes a bruising running style with breakaway speed, and hes the first player since the 1970 merger to rush for 200 yards in two of his first three career starts. He has the only 200-yard games in the NFL this season, and his averages of 6.4 yards per carry and 4.1 yards after contact lead the league .Thats a big man running hard, not slowing down, sticking his foot in the ground, getting north, first-year Miami coach Adam Gase said. Hes running through arm tackles, and all of a sudden we started getting all these explosive plays.Fans, the media and flattened defenders ask the same question: When did this guy come from?Ajayi (pronounced uh-JYE-ee) was born in London to Nigerian parents and is a British citizen with lots of family and friends in England. He speaks with a British accent, and sounds particularly English when asked if hes the best soccer playeer on the Dolphins.ddddddddddddI would believe so, he said with a smile.Lately hes their best football player, too. He moved to the United States in grade school unfamiliar with the game, but soon took it up while also playing soccer.The divided attention slowed his progress.My dad sat me down and was telling me to decide on one, because, he told me, I could be good at both, or be great at one, Ajayi recalled.Showing the instincts of a good running back, he chose the right path. After starring in high school near Dallas, Ajayi went to Boise State, where he became the first FBS player to total 1,800 yards rushing and 500 receiving in a season.The Dolphins waited until the fifth round to draft him in 2015, and even then the pick was critiqued as a reach, because of doubts about his durability because of a knee issue.Ajayi came off the bench in nine games as a rookie and totaled 187 yards rushing. He was anointed a likely starter this season after Lamar Miller departed in free agency, but during training camp, Gase perceived a misplaced sense of entitlement regarding playing time and became increasingly annoyed.When the Dolphins opened the season at Seattle, Ajayi didnt even make the travel roster.We had a rough 10 days, Gase said. But he centered himself and then started over.In Week 5, Ajayi made his first start and became hard to stop. He blossomed into the Dolphins Great Briton, and teammates now rave about his resilience and relentlessness.To play the way hes playing, it just makes me smile every time I think about it, Pouncey said, because a lot of guys would have tanked and gone the other way, getting benched right after thinking youre starting the season off.Gase is optimistic he can keep his international celebrity humble, hungry and healthy. In interviews, Ajayi seems genial, modest and a little overwhelmed by all the attention hes getting, whether from the BBC or school friends he had lost touch with.Im learning a lot about myself, he said. Im taking each week by itself, and just pushing to get through what happened earlier this year, and moving forward from that. Being in this position, it feels good, and we just want to keep building off that and not be satisfied.Celebratory dinners can wait.---AP NFL website: www.pro32.ap.org and http://twitter.com/AP-NFL---Follow Steven Wine on Twitter: http://twitter.com/Steve-Wine.
