Per a Bobcats news release:
Charlotte Bobcats center Joel Przybilla will be sidelined for the remainder of the 2010-11 season after continued pain and immobility in his right knee.
Last season, Przybilla had season-ending surgery to repair a ruptured patella tendon. He will undergo an additional procedure to remove surgical hardware (wires) that were inserted to help attach and repair the tendon.
A 7-1 center, Przybilla was selected by Houston with the ninth overall pick in the 2000 NBA Draft before having his rights traded to Milwaukee. In 553 NBA games with Milwaukee, Atlanta, Portland and Charlotte, he holds career averages of 4.0 points, 6.3 rebounds, and 1.5 blocks, while connecting on .568 from the field. Przybilla has also appeared in 10 career postseason games with the Bucks and Trail Blazers.
This season, he has appeared in 36 games total, including five with the Bobcats, with averages of 1.8 points and 4.0 rebounds in 14.4 minutes.
The Bobcats acquired Przybilla along with forwards Dante Cunningham and Sean Marks, two first-round draft picks and cash considerations from Portland on February 24, 2011 in exchange for Gerald Wallace.
