THOUSAND OAKS, Calif. -- Bernhard Langer has a left knee injury that could force him to withdraw from the PowerShares QQQ Championship, the inaugural Charles Schwab Cup Playoffs event.Im not sure Ill be able to play tomorrow, but Ill make that call at noon when my tee time is, Langer said Thursday. For right now, Ive been getting treatment and trying to stay off my knee.Simply, the decision will come down to whether he can hit the ball.I tried yesterday and it didnt work, Langer said. I cant transfer my weight. I cant put any pressure on my left knee.The 59-year-old German star leads the 50-and-over tour with four victories and has wrapped up the season money title with $2,697,459.I had an MRI on Monday because I couldnt walk properly and just had problems, Langer said. Obviously, havent hit a shot yet, havent been out on the course. I walked it, but I havent hit a shot yet because I cant, I cant put much pressure on my knee. Walking these hills is very difficult, especially downhill.The top 72 players on the money list earned a spot at Sherwood Country Club, the former site of Greg Normans Shark Shootout and Tiger Woods event that is now called the Hero World Challenge. The playoff field will be cut to 54 for the Dominion Charity Classic next week in Richmond, Virginia, and to 36 for the Charles Schwab Cup Championship the following week in Scottsdale, Arizona.Each dollar earned in the first two events is worth two points and will be added to the regular-season total. At the Charles Schwab Cup Championship, points will be reset so that any golfer in the top five can capture the Charles Schwab Cup with a win. Langer has a big enough advantage over second-place Miguel Angel Jimenez that he would keep the lead in the standings even if he doesnt play this week.I came all the way here from south Florida and committed to play, said Langer, a three-time Cup champion. But if Im going to do long-term damage, the last thing I want to do is try and play and do further damage and then I cant play next week or the following week, which that would really be bad if I cant play the Schwab Cup. You know, the priority is to get my health. You cant play golf if youre not healthy. The game is hard enough when youre healthy; you dont need to be injured.Fred Couples is attempting to play after sitting out eight months with a back injury.Im honestly hoping to get through this, the 57-year-old Couples said. Its one of my favorite golf courses, so I found out last week that I was in the playoff. I havent played since February, so I thought, You know, Ill commit. I hit balls on Friday before I committed and actually felt OK.John Daly qualified 70th. He has five top-25 finishes in 14 starts since turning 50.All of us old guys have seen this course a few times, so theres no home-field advantage, Daly said.

RIO DE JANEIRO -- Defending Olympic champion Rosie MacLennan opted for her easier routine during womens trampoline finals on Friday, a rare moment of caution in a sport that thrives on daring.I was a lot more confident in it, MacLennan said. The other one was a little more shaky. I knew it would be a bit of a gamble and the Olympics isnt a time to gamble.Considering what MacLennan has been through over the last year as she recovered from a pair of concussions that threatened her career, hard to blame her. Yet she never lost faith, and it paid off with a second gold medal to bookend the one she captured in London.Soaring effortlessly and precisely through the air inside the Rio Olympic Arena, MacLennan posted a score of 56.465 to become the first Canadian athlete to win gold medals in consecutive summer games. Bryony Page of Great Britain was second, followed by Li Dan of China.Page admitted she was shellshocked and could barely stand after putting together the best set of her life, the 25-year-olds legs buckling when her score posted.MacLennans response was more measured. Shes been here before, even if she wasnt sure she would be back after sustaining two concussions in the span of a month in 2015. The first one came during a training mishap, the other when her head was smacked by a car door.Her recovery was slow. Though she managed to qqualify for Rio by finishing fourth at the world championships last November, she noticed an odd and troubling symptom when she ramped up her training program early this year: her eyes would start shaking in the middle of her routine.ddddddddddddIf you cant spot the trampoline you dont know where you are and I was afraid of getting lost in skills, MacLennan said. That fear and that uncertainty took a long time to get back.It wasnt until March that MacLennan felt her confidence return. Working methodically so she wouldnt get too far ahead of herself, MacLennan felt the trust in her talent return.In some ways it was really tough but it was also a reminder of how much I really did love the sport, she said. If I didnt I would have given up.Instead she pressed on in an event that requires gymnasts to leap two stories in the air 20-25 times over the course of a minute, getting scored on a combination of air time and their series of 10 connected flips and twists. MacLennan placed third in qualifying.Another shot at gold on the line, she could have taken the riskier route and hoped the difficulty would offset any mistakes in execution. Pragmatism won out, a decision that ended with her atop the medal stand once again. ' ' '
