SANTA CLARA, Calif. custom cowboys jersey . -- San Francisco 49ers offensive lineman Mike Iupati sustained a sprained ligament in his left knee Sunday at New Orleans and it isnt considered to be season-ending, a person with direct knowledge of the injury said Wednesday. An MRI this week revealed the sprained medial collateral ligament, and Iupati isnt expected to need surgery, the person said, requesting anonymity because the 49ers didnt reveal specifics on what happened to Iupati. He walked to the sideline with assistance in the third quarter of a 23-20 loss at the Superdome and then was carted off to the locker room. The injury happened when running back Frank Gore got tackled into the back of Iupatis left leg. The 26-year-old Iupati, a staple in San Franciscos veteran, much-improved O-line, has started every game since the 49ers selected him 17th in the 2010 NFL draft out of Idaho. That run would end if he isnt able to play Monday night at Washington. "I dont know the timetable or how much time he might miss," the person said. "Im not sure Mike knows. Theyre still evaluating him." Iupati wasnt in the locker room during the portion open to reporters Wednesday, when the reigning NFC champion Niners (6-4) cancelled a scheduled walk-through because of a downpour and moved their preparations for the Redskins indoors. Coach Jim Harbaugh will next address the media Thursday. Adam Snyder, who didnt speak to reporters, would be the likely substitute to replace Iupati. "Mikes a great player, a Pro Bowl player," running back Frank Gore said Wednesday. "He helps out our running game a lot, but Snyder is a vet player. Hes been playing since he was a rookie. Hell be fine. But we will miss Mike. I think Snyder can come in and play." Demarcus Lawrence Blue Jersey . The Reds won for the 12th time in 17 games and extended their NL Central lead over Pittsburgh to three games. The second-place Pirates lost for only the third time in their last 11 games. Cueto (6-3) left with a 5-1 lead in the eighth. Andrew McCutchen hit a three-run homer off Logan Ondrusek two pitches later. Deion Sanders Blue Jersey . According to some observers, the 102-90 victory over the hapless, short-handed Milwaukee Bucks didnt rate because the expected lopsided blowout didnt materialize.HOUSTON -- James Harden believed his miscues were partially responsible for the Washington Wizards getting back into the game after the Rockets built a huge third-quarter lead on Wednesday night. So with the game on the line late, Houstons star was determined to atone for his earlier mistakes. "I had to figure a way to make it even," Harden said. He did. Harden scored 35 points and his layup with 0.7 seconds remaining lifted the Rockets to a 113-112 win over the Wizards, sending Houston into the All-Star break with a season-best seven-game winning streak. John Wall gave Washington the lead with a pair of free throws with 4 seconds left. Trevor Ariza fouled out when he pushed Harden to the ground on the ensuing inbounds pass. It was ruled a foul away from the play, giving Houston one free throw and possession. Harden, who was 16 for 16 at the line, made the free throw before grabbing a pass from Chandler Parsons and driving into the lane for the winning shot. Harden was asked to explain his work on the last play. "Get to the rim and make the play," he said. "Its simple." The Wizards had a chance to win at the end, but Kevin Seraphins shot clanged off the rim. Ariza had 11 rebounds and a season-high 32 points with a career-best and franchise-record 10 3-pointers to lead the Wizards. "Its too bad, these guys deserved to win that game," Washington coach Randy Wittman said. "To have it taken from them like that, its sad." Houston won despite committing a season-high 26 turnovers that led to 24 points by the Wizards. The Rockets were helped by making 35 free throws while Washington hit only eight. The Wizards trailed by 18 in the third quarter before a barrage of 3s from Ariza got his team back in the game. His 10 3-pointers were the most ever against the Rockets. Ariza was 7 for 7 on 3s in the third and made six in a 4-minute span late in the quarter, including three in an incredible 32-second stretch. Five straight points, capped by a three-point play by Wall, put the Wizards up 110-108 with 2:21 remaining in the fourth. Houston had a shot-clock violation on the next possession, but Nene fouled out with an offensive foul on the other end. Harden made two free throws with 223. Tony Dorsett Blue Jersey. 2 seconds left to tie it at 110. Nene had 21 points, Bradley Beal scored 20 and Wall finished with 19 points, 14 assists and three steals. Dwight Howard added 24 points with 16 rebounds for Houston, and Parsons scored 18. An 8-3 run by Washington cut Houstons lead to two midway through the fourth quarter. The Rockets scored the next five points to stretch the lead before five quick points by Washington got it back down to two with 4 minutes left. A 3-point shot by Beal got Washington within five with about 9 minutes left in the third quarter. The Rockets scored 13 straight points after that to extend the lead to 83-65. Harden had five points in that stretch, and he and Howard brought the crowd to its feet when Harden found the big man for a monster alley-oop dunk. The Wizards missed shot after shot and didnt score four more than 4 minutes while Houston built the lead. They missed from long-range, mid-range and even botched two layups. Washington finally ended the scoring drought thanks to Ariza. He made his second 3-pointer of the quarter with less than 5 minutes left in the third. He made three more 3s on consecutive possessions a couple of minutes later to cut Houstons lead to 90-79. But he wasnt done yet, and made two more on back-to-back trips down the court to make it 93-87 with a minute remaining in the quarter. Wall got in on the fun on the next possession, sinking a 3 of his own, to leave Houston clinging to a 93-90 lead entering the fourth quarter. Ariza seemed unimpressed by his big night. "I was open and there were good looks and I was just letting them fly," he said. The Rockets used a 10-3 spurt to regain a 52-46 lead late in the second. Howard and Harden each made two free throws in the last 30 seconds of the half to extend Houstons advantage to 63-54 at the break.
