The rehabilitation of Greg Oden and his right knee is officially over.

Now, it's all about basketball.

So on Monday, the Blazers' 2007 No. 1 overall draft pick who missed all of last season because of a knee injury, began the latest and most significant step in his comeback. He practiced for the first time in full-contract drills, going up against teammate Channing Frye for 45 minutes at the Blazers' practice facility in Tualatin.

For moments, it was awe-inspiring. Early in the workout, Oden took a long stride and ripped at the rim with such ferocity that the shot clock mounted on the backboard shook for more than five seconds punctuating one of his dunks.

"I've got tingles," assistant general manager Tom Penn said from his courtside seat.
