SANTA CLARA, Calif. Jason Terry Jersey . -- After getting run over for three straight weeks by backs such as Ezekiel Elliott, David Johnson and LeSean McCoy, the beleaguered San Francisco 49ers run defense may have caught a needed break.Tampa Bay back Doug Martin suffered a setback in his rehabilitation from a hamstring injury and might not be able to make it back in time for the Buccaneers (2-3) to play Sunday in San Francisco (1-5).It might not matter much since the Niners also allowed 100-yard games by lesser backs such as Fozzy Whitaker and Christine Michael during a five-game run of futility on run defense that has San Francisco on pace to allow the most yards rushing in a season since the 1985 Houston Oilers.Were all stunned, safety Antoine Bethea said. We havent been playing to our potential, havent been playing to the standard we set for ourselves.Things might have bottomed out last week in Buffalo when McCoy ran for 140 yards and three TDs and the Bills gained 312 yards in all on the ground in the second-worst rushing defense performance in 49ers history.Quite frankly, Im embarrassed by what happened on this past Sunday, defensive coordinator Jim ONeil said.While missing Martin could be a break for San Francisco, backup Jacquizz Rodgers is coming off the best game of his career with 30 carries for 101 yards two weeks ago against Carolina.That was the first time all season that the Bucs topped 100 yards rushing as a team in a game.Your run game gets better if you run it more, Tampa Bay coach Dirk Koetter said. Youve got to make yards, youve got to have efficient runs and youve got to be moving the chains. If youre doing that and youre running it more and youre repeating runs, your line and your backs both have a tendency to get stronger as you go.Here are some other things to watch on Sunday:KAP, PART 2: Colin Kaepernick made his first start at quarterback for the 49ers in nearly a year last week. He went 8-for-11 for 135 yards in the first half against the Bills, but struggled in the second half when he was just 5-for-18 for 52 yards and took three sacks. Kaepernick did show flashes as a scrambler with 66 yards rushing on eight carries, but knows its a fine line of when to stay in the pocket and when to run.There were a couple times that I wish I would have hung in a little bit more, but those are always split-second decisions that its always easier to look back and say, `I should have done this. I should have done that, he said.NO ACTION FOR JACKSON: The Bucs will be without receiver Vincent Jackson, who was placed on IR this week with an injured left knee. The three-time Pro Bowler had 15 catches for 173 yards in five games this season. His absence will allow defenses to pay even more attention to star receiver Mike Evans.When you lose a guy like Vincent to your team, he means a lot to our team because of the kind of pro he is, the kind of player he is and the kind of man he is, Koetter said.The Bucs do hope to get defensive tackle Gerald McCoy back from a calf injury that forced him to miss the previous game.THIN BACKFIELD: The Niners also could be without their starting back with Carlos Hyde expected to miss the game with a shoulder injury. That will leave the running duties mostly to Mike Davis and Shaun Draughn. Davis averages just 1.7 yards per carry on 47 career runs, while Draughn averages just 2.1 yards per carry this season and 3.3 in his career.BAY AREA DEBUT: Bucs QB Jameis Winston is set to play his first game ever in the San Francisco Bay area. But if he had to do it all over again, he might be more familiar with the region. Winston was accepted to Stanford out of high school and visited the school, but decided to sign with Florida State instead. Despite winning a Heisman Trophy and national championship with the Seminoles, Winston said in retrospect he might have chosen differently.Stanford is a great school, he said. You are who you put yourself around. Id have loved the opportunity to go to Stanford and be with some of my friends out there.RIGHT THE SHIP: After the Niners opened the season with a 28-0 home win over the Rams, little has gone right for first-year coach Chip Kelly. The team has lost five straight games for the first time since 2010 and is in danger of its first-six game skid since 2008, which led to Mike Nolans firing.The deal in this league is everything being so close, its in the details, Kelly said. Its in the little tiny things that separate winning and losing in this game and winning and losing is extremely close.---Online:AP NFL website: www.pro32.ap.org and www.twitter.com/AP-NFL Delon Wright Jersey .

Durant finished with 24 points and 13 rebounds, Jackson matched his career high with 23 points on 10-of-14 shooting and Lamb scored 12 points on 5-of-7 shooting, lifting the Thunder to a 94-88 win over San Antonio and snapping the Spurs 11-game winning streak. Pakistans performance in the five ODIs against Australia in January could determine Azhar Alis future as captain with PCB chairman Shaharyar Khan saying the board had lost its trust in him. He added that Sarfraz Ahmed, who leads the T20 side, was a strong option to take over the captaincy, perhaps in all three formats whenever Misbah-ul-Haq retires from Test cricket.Azhar has had a tough 19 months since he was appointed ODI captain in March 2015, soon after the World Cup. In his tenure, Pakistan had slipped to ninth place on the ICC rankings, with the 86 points they had being their lowest tally since the system was introduced in 2001. They have won only four out of nine series with Azhar in charge, two of them coming against Zimbabwe and Ireland.In September, following a 4-1 defeat to England, Shaharyar asked Azhar to considering resigning. But Azhar preferred not to and led Pakistan to a 3-0 whitewash of West Indies in the UAE. However, Shaharyar and the PCBs doubts continued.We are more than happy with Azhar as a player, human being and a person, he said in Karachi. But his leadership skills have not given us confidence and his place in ODI side is on shaky ground. It is also a fact that we had left it up to him to step down as captain during the England series but after a collective decision we decided to allow him to carry on for the West Indies series.Its really tough to make a decision after a captain won it by 3-0, but still I believe its purely Azhars own decision to leet it go and he earlier refused to relinquish his captaincy. Cheap Mavericks Jerseys. Shaharyar said the board had asked head coach Mickey Arthur about his opinion on Azhar as captain and he too had voted in favor of a change and having Sarfraz in charge.Sarfraz is a strong option because we might even consider him for all three formats as captain. In our culture, it is always best to have one captain for all three formats in Pakistan cricket and historically it works for us. We dont like to force anyone to take decisions we dont work like that. And we would like to see a senior player go out with honor and respect.The PCB was also on standby with regards to Misbah, who is yet to take a decision over how long he could continue playing for Pakistan. The three Tests against Australia may be his last. Before flying for the tour, Misbah had said he would take a call based on whether he felt he could still contribute to the team. Misbah is a top-class captain and performer and has led the side well. Even at 42, he is super fit and I told him recently it was his decision when to retire, he said. But we have also made our mind on possible back-ups if the tour does not go well.Shaharyar understood that leaving the game can be a difficult decision. It is true because for a top player it is always hard to leave the adulation and fame. But we would like to see that change. ' ' '
