MIAMI GARDENS, Fla. -- Ryan Tannehill watched the final play from the sideline, hopping anxiously as an opponents desperation heave hung in the air, then letting out a jubilant scream when a teammate swatted the ball to the turf. At the end of a dismal week, the Miami Dolphins finally had something to celebrate. Brent Grimes broke up Philip Rivers final pass in the end zone as time expired, and the embattled Dolphins beat the San Diego Chargers 20-16 Sunday. Tannehill threw for 268 yards, including a 39-yard score to Charles Clay, who broke two tackles on the play. Miami managed 104 yards rushing behind a makeshift line. The victory came amid a harassment scandal that raised questions regarding the teams locker room culture. An NFL special investigator will question players this week about the relationship between offensive tackle Jonathan Martin and guard Richie Incognito. "Theres a lot going on, but were not focused on that," Tannehill said. "Were focused on football." The Dolphins (5-5) won for only the second time in the past seven games. Theyre still in contention for an AFC wild-card berth, despite a dreadful defeat last Monday at Tampa Bay and the distractions of the harassment case. "Were fighting through this," tackle Tyson Clabo said. "Someones got to get that last wild-card spot. Why not us?" The Chargers (4-6), who were plagued by penalties and missed tackles, lost their third game in a row. "We made too many mistakes from start to finish," coach Mike McCoy said. "We hurt ourselves way too much." Trailing by four points, San Diego started from its own 17 with 1:54 left and drove to the Miami 25. On the final play, a harried Rivers lofted a pass toward Vincent Brown in the end zone, but the 5-foot-10 Grimes leaped to slap the ball away. Rivers threw for 298 yards and Ryan Mathews ran for 127, including a career-best, 51-yard dash to set up a field goal. But the Chargers had 10 penalties for 76 yards, including two infractions that cost them 11 points in the first half. "Ten penalties, thats a lot," Rivers said. "Were not playing well enough to overcome those things." Miami played at home for the first time since the scandal broke. The stands were less than two-thirds full, and an airplane banner reflected the mood by calling for the firing of general manager Jeff Ireland, who has long been in disfavour with fans. Because centre Mike Pouncey missed the game with an illness, the Dolphins had three backups starting on the offensive line. Martin missed his third consecutive game while undergoing treatment for emotional issues, and the suspended Incognito sat out his second game. Working behind the patchwork line, Tannehill was sacked four times, increasing his NFL-high season total to 41. But Miami averaged 5.5 yards per rush to limit the Chargers time of possession. As usual, the Dolphins went with pass plays two-thirds of the time. On the games opening drive, they marched 76 yards -- with all but 2 coming through the air -- for a field goal. Penalties repeatedly hurt the Chargers. Corey Liuget was flagged for roughing the passer to negate a teammates fumble recovery at the San Diego 1, and two plays later the Dolphins scored a touchdown for a 10-7 lead. Liuget said he didnt see Tannehill get rid of the ball. "It was a costly penalty for us," Liuget said. "I wish I could get that one back. Its not a great feeling at all." A scrambling Rivers hit Antonio Gates for a 5-yard touchdown with a minute left in the first half, but the quarterback was flagged for throwing past the line of scrimmage, and the Chargers settled for a field goal that made it 10-all at halftime. A drive in the second half stalled after receiver Keenan Allen was flagged 15 yards for taunting, and the Chargers defence was penalized four times for offsides. San Diegos Derek Cox dropped a potential pick-six in the first quarter, and on the next play Johnny Patrick intercepted Tannehill at midfield. The Chargers scored four plays later for a 7-3 lead. Clay put Miami ahead to stay in the third quarter when he caught a short pass and ran over defenders Marcus Gilchrist and Donald Butler en route to the end zone, making it 17-10.

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.&quuot; The question is whether Williams will continue to develop alongside Byrd.dddddddddddd 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. ' ' '
