Portland center Joel Przybilla will miss the remainder of the season after injuring his right knee on Tuesday.

Przybilla had surgery Thursday to repair his ruptured right patella tendon.

The Blazers have been hit hard by injuries this season.

They are already without center Greg Oden (left knee), forwards Nicolas Batum (shoulder), Travis Outlaw (left foot) and Rudy Fernandez (back), and rookies Patrick Mills (right foot) and Jeff Pendergraph (hip).
