WASHINGTON (AFP) - Tiger Woods expects to play in next month's US Open despite nagging left knee pain that forced him out of last week's US PGA Players Championship and has him doubtful for the Memorial in two weeks. "Bummed that my left leg has me on the side-lines, but I want, and expect, to be at the US Open. Will do all I can to get there," Woods posted Monday evening on his Twitter microblogging website. Woods suffered a sprained left knee and strained left Achilles tendon in the third round at last month's Masters, the year's first major championship where he finished in a share of fourth for the second year in a row. In an update on his official website, Woods said he suffered no new damage to his leg last Thursday at the Players when he fired a six-over par 42 on the front nine and withdrew because of left leg pain. While Woods said he has no timetable for when he might return, he called it unlikely that he would play June 2-5 at the Memorial, a tournament hosted by Nicklaus that serves as a major tune-up for top US Open contenders.
