RIO DE JANEIRO, Brazil -- UFC featherweight champion Jose Aldo (23-1) successfully defended his belt for a fifth consecutive time, earning a fourth-round stoppage over Chan Sung Jung (13-4) in the headlining bout of Saturdays UFC 163 fight card at HSBC Arena. China Jerseys Authentic . Aldo looked comfortable for most of the championship contest, standing firm in the pocket and offering stiff counter shots each time Jung moved forward with flurries of kicks and punches. A few takedowns late in the opening round earned Aldo additional points, and he was up big on the judges cards heading into the championship rounds. The champion did seem to slow as the bout wore on, taking a few deep breaths and stalling out in a few wrestling positions against the cage. But just as Jung turned up the heat to try to capitalize, his right shoulder dislocated during an errant punch, leaving the challenger vulnerable. Aldo sensed the opening and unleashed a series of high kicks that crashed into the arm and sent Jung to the ground. Aldo immediately pounced with more punches from the top, and referee Herb Dean waved off the fight at the 2:00 mark of the fourth round. Jung immediately turned over and grabbed his shoulder, grimacing through the pain. "I did see that he separated his shoulder, so I kicked him and tried to put him down on the ground to give him some ground and pound," Aldo said. As it turned out, Jung wasnt the only one who suffered an injury, as Aldo revealed at the post-event press conference that he had suffered a potentially broken foot on the first kick of the fight. With the victory, Aldo is now riding a 16-fight win streak and remains the lone featherweight champion in UFC history. Jung sees a three-fight win streak snapped and falls short in a bid to become the first Asian-based champion in UFC history. In the nights co-feature, Phil Davis (12-1) earned a unanimous-decision nod against former UFC champion Lyoto Machida (19-4) in a hard-fought three-round affair. A vaunted wrestler, Davis struggled to get the action to the floor until very late in both the second and third rounds. Davis stayed busy on his feet, kicking the legs and body while doing his best to avoid Machidas counterpunches. Meanwhile, Machida looked very comfortable on his feet but never really overwhelmed Davis with his striking, leaving all three of the rounds relatively closely contested. In the end, judges gave Davis the unanimous-decision nod, 29-28 on all three cards, in a result that proved wildly unpopular with the Brazilian crowd. "Ive been a fan of Lyoto Machida since I started in the UFC. This man is awesome," Davis said as the crowd booed. "The late takedowns definitely helped. Its just part of what I do." In middleweight action, "The Ultimate Fighter: Brazil" winner Cezar Ferreira kept his UFC record perfect with a 47-second submission win over first-time UFC fighter Thiago Santos. Ferreira landed an early left hand that wobbled his opponent, and he followed with a quick high kick. With Santos hurt, Ferreira jumped forward, locked in an arm-in guillotine choke and rolled until he could get a firm squeeze. Trapped in the choke, Santos had no choice but to tap. The whole process took just 47 seconds. Fighting in the UFC for the first time nearly four years, Rio de Janeiro native Thales Leites (21-4) earned an impressive unanimous-decision win over British slugger Tom Watson (16-6). Leites outgrappled Watson throughout the 15-minute affair, repeatedly bringing the action to the floor and keeping his opponent out of his comfort zone. Watson showed great heart by battling through a handful of impressive submission attempts, but Leites was awarded the unanimous-decision win. "I tried submitting him; unfortunately I didnt," Leites said. "He did a great job blocking me in the first round and came back stronger for the second, but I was ready." In the nights card-opening contest, flyweight contender John Lineker (22-6) earned his third-straight win with a second-round TKO over promotional newcomer Jose Maria (33-4). Despite the impressive performance, Linekers chances of receiving a title shot for the victory seem slim after failing to make weight for the second time in four UFC appearances. "I must say its always a bit upsetting facing a fellow Brazilian," Lineker said. "He also went through a lot in his life, and taking this away from a countryman is a bit sad."

PITTSBURGH -- The Pittsburgh Steelers put themselves back in the playoff conversation by stringing together four convincing victories in which they never trailed. They put themselves on the cusp of the AFC North title by showing the kind of resilience theyve lacked this year when things get tight.Down two touchdowns on the road, the Steelers didnt panic. They didnt press either. They simply kept chipping away at the seemingly emotionally fragile Bengals until Cincinnati lost its composure and, eventually, whatever resolved remained in an otherwise lost season.The result -- a 24-20 victory that set up a de facto AFC North title game next Sunday against Baltimore -- was Pittsburghs first win in a game decided by less than seven points this season and first when trailing at the half since Week 15 of last year.It just shows what were capable of, safety Sean Davis said Monday. Were a team that fights. Weve been through so many things throughout that game and it does nothing but make us more confident and lets us know when we play like that the whole game were a tough team to beat.A team that evolved from one heavy on flash to something more substantive over the last month. Six Chris Boswell field goals, one well-timed Boswell trip of Cincinnati returner Alex Erickson that prevented a touchdown and an exclamation point game-ending drive gave the Steelers (9-5) their longest winning streak since 2009.Leading by four with 5:53 remaining, Pittsburgh took over at its own 16 and the Bengals never got the ball back. Four first downs -- the last coming on Cincinnatis eighth penalty of the day -- allowed Ben Roethlisberger to kneel down four times and give the Steelers their 15th win in 18 trips to Paul Brown Stadium.Its huge, guard David DeCastro said. Having those team wins, especially late in the season. Thats got to be the way to do it.Maybe thats why occasionally nitpickyy head coach Mike Tomlin opted not to be so nitpicky after his team improved to 11-1 in its last 12 December games. China Jerseys For Sale. While allowing most of his teams issues early on Sunday were of the self-inflicted variety, from the face mask by defensive end Stephon Tuitt that extended Cincinnatis opening drive to the pass interference call in the end zone on rookie cornerback Artie Burns that set up a Bengals touchdown.Its not the first time this season the Steelers have struggled on the road. It is the first time theyve managed to overcome it.We have played that team five times in the past twelve months, its not a lot of secrets, Tomlin said. Its just technical expertise and a lot of butt kicking. And smiling in the face of adversity.Something Pittsburgh is becoming more comfortable at as the long slog of the regular season morphs into a sprint. The most basic math is very simple: knock off the Ravens (who have won four straight in one of the AFCs most heated rivalries) and the Steelers have a third straight playoff berth for the first time in Tomlins 10-year tenure.Its a position Pittsburgh envisioned all along, it not the winding path it took to get here. The four-game nap the Steelers took in the middle of the season appears to be a distant memory.Were going to fight for the whole 60 minutes, Davis said.If the can do it for 60 more, theyll be division champions.Game notes Tuitt underwent an MRI on his right knee on Monday.
