The Oregonian (Joe Freeman) reports (via blog): The news just keeps getting worse for Trail Blazers rookie Greg Oden and his mysterious ailing left knee. The Blazers, after evaluating their starting center earlier in the day, announced Monday evening that Oden will miss another seven to 10 days because of his lingering left knee issues. Oden, who chipped his knee cap when he banged knees with Golden State’s Corey Maggette Feb. 12 in Oakland, has missed the Blazers’ last seven games. According to the Blazers’ latest timeline, Oden will miss between four and six more games, which includes pivotal matchups against playoff contenders Denver, Dallas and the Los Angeles Lakers. If he sits out the maximum 10 days, Oden will return just before the team’s five-game East Coast trip later this month.
