John Daly collapses with scary knee injury

John Daly withdrew from the PowerShares QQQ Championship on Saturday after collapsing on the ninth hole with an injured right knee. The 51-year-old was helped off the course and was unable to put any weight on the knee. The severity of the injury was not immediately clear.

For Daly, who was in contention at 4-under at the time of his injury in Thousand Oaks, Calif., it appears to be the most significant blow of his recent knee problems. Daly withdrew from last week’s event, too, citing his knee and saying he had arthritis. He said he would be getting a cortisone shot to get ready for this weekend.

Without the cult-hero golfer in the running, Bernhard Langer shot his second straight 3-under 69 Saturday to pull into a tie with David Toms and Miguel Angel Jimenez for the second-round lead.
