LAS VEGAS -- Middleweight champion Chris Weidman has a knee injury, forcing the UFC to postpone his title bout against Lyoto Machida for six weeks. The UFC announced the changes to two major Las Vegas shows on Monday. Weidman (11-0) was expected to make his second title defence at UFC 173 on May 24 at the MGM Grand Garden, but the Long Island-based mixed martial artist needs minor surgery. Weidmans bout with Machida is moving to UFC 175 on July 5 at the Mandalay Bay Events Center. The UFC hasnt decided on a new main event for its traditional Memorial Day weekend show. Former heavyweight champion Junior Dos Santos will meet Stipe Miocic in the top undercard fight on the pay-per-view event. Weidman claimed the 185-pound title when he stopped long-reigning champion Anderson Silva in the second round last July. He defended the belt in December when Silva broke his leg in their rematch. Weidman is the fourth champion in the UFCs seven mens weight classes currently sidelined for surgery, although his recovery is expected to be the shortest. Heavyweight champion Cain Velasquez had shoulder surgery in December, and isnt expected to return to the octagon until late this year. Lightweight champion Anthony Pettis has been out since last August following knee surgery, and is hoping for a late-summer return. And welterweight champion Johny Hendricks is likely out until fall after tearing his right biceps muscle two weeks before his victory over Robbie Lawler this month. Machida (21-4), the former UFC light heavyweight champion, got this middleweight title shot after Vitor Belfort was removed from the card in late February when the Nevada Athletic Commission banned the use of testosterone replacement therapy. Belfort was among MMAs most prominent sanctioned steroid users, but has decided to give up the practice. Machida, a karate expert from Brazil, has won two straight fights after dropping down to 185 pounds. Tahir Whitehead Jersey . - Young and old. Kyle Wilber Jersey .

The same for both the Calgary Flames and the Edmonton Oilers. CLEVELAND -- Dont ask Maurice Cheeks why his team is so successful away from home. The Detroit Pistons coach cant explain it. "I dont have any theories why that is," he said. "I just dont know." Josh Smith scored 25 points, Brandon Jennings added 21 and the Pistons continued their domimant play on the road with a 115-92 win over the Cleveland Cavaliers on Monday night. The Pistons have won seven of their last eight away from home, including victories against defending NBA champion Miami and Indiana, which has the best record in the Eastern Conference. While Cheeks cant come up with a reason, reserve guard Chauncey Billups, a veteran of 17 seasons, managed to put his finger on something. "On the road, all we have is us," he said. "We know we have to stick together when their crowds get going and they go on runs." The Pistons went on plenty of runs in their latest road success. Detroit went ahead for good midway through the first quarter and built a 21-point lead late in the first half. The margin reached 28 points in the fourth quarter as the Pistons rolled to their biggest win of the season. Jennings also had 13 assists for Detroit, which placed seven players in double figures. Kyrie Irving scored 21 points for Cleveland, which has lost four of five. "We got our butts handed to us tonight," said forward Tristan Thompson. The Cavaliers had shown signs of progress earlier this month, winning three straight and five of six. Cleveland has struggled since, dropping close games to Miami and Portland and losing by 16 points to a short-handed Chicago team on Saturday. "Our sense of urgency the last two ballgames has been non-existent," Cleveland coach Mike Brown said. Cavaliers centre Andrew Bynum was scoreless in 22 minutes, missing all 11 shots from the field and getting seven rebounds. Detroit is 6-10 on its own court and was coming off home losses to Charlotte and Houston, but took control early. Smith scored 10 points in the first quarter when Detroit shot 56 per cent. Smith hit 3-pointers on back-to-back possessions late in the second quarter that stretched the lead to 56-35. The Pistons were 22 of 41 from the field in the first half and took a 58-40 lead tto the locker room.dddddddddddd Cleveland cut the lead to 10 points in the third quarter, but three baskets by Jennings, including two 3-pointers, five points by Smith and dunks by Andre Drummond on consecutive fast breaks extended the lead back to 89-64. Smith was 10 of 18 from the field and had eight rebounds and three assists in 31 minutes. "Working in the paint is the strength in our game, so Im making a conscious effort to not settle for shots," Smith said. "Im used to being a little selfish, but I can be a distributor when other guys get hot." Jennings directed the offence with 13 assists. Drummond had 14 points and 11 rebounds while Greg Monroe scored 11 points and had 11 rebounds. Reserves from both teams played most of the fourth quarter. Thompson scored 17 points for the Cavaliers. Cleveland played without guard Dion Waiters, the teams second-leading scorer, for the third straight game because of tendinitis in his right wrist. Brown is still searching for answers to get his team to play with more consistency. The loss was Clevelands biggest at home since a 125-90 defeat against San Antonio on April 3, 2012. "I dont know if we mentally understand what it takes to keep doing this every time we step out on the floor," he said. "Were getting hit in the mouth right now and Im interested to see if we can respond the right way." The Pistons have won seven in a row against the Cavaliers, including four straight in Cleveland. Cheeks coached his 600th career game. He has also coached for Portland and Philadelphia.
