Joel Przybilla, thrust into Portland's starting lineup earlier this month after Greg Oden was lost for the year with a fractured kneecap, landed awkwardly while going for a rebound in the first quarter of Tuesday's game against the Mavericks.

Simply looking at his misshapen kneecap as he writhed in pain suggested a serious injury, not long after he was helped off the court and examined by doctors, the team confirmed he suffered a ruptured right patella tendon and dislocated patella. He's "sidelined indefinitely," which is merely a polite way of saying he's almost certainly done for the year. (Kevin Pelton and Will Carroll of Basketball Prospectus discuss the severity of the injury and how it compares unfavorably to Oden's injury.)
