Olympiacos Pireaus on Tuesday announced that forward Josh Childress will undergo hernia surgery today and miss most, if not all, of the Top 16. Childress (203, 25) is the third-best scorer (10.7 ppg.) and second-best rebounder (5 rpg.) for the Reds, while leading the team in minutes played (26.3 mpg.). Childress returned to the United States over the weekend for medical attention concerning an inguinal hernia. It was decided that he would undergo surgery for the problem on Tuesday at Hahnemann University Hospital in Philadelphia, Pennsylvania. The club statement said that Childress is expected to return to action in approximately 40 days. Childress had already missed the last Euroleague regular season game played by Olympiacos, a home loss to Le Mans, as well as the team's last Greek League game. Childress spent the first four seasons of his professional career as a double-digit scorer with Altanta of the NBA and three seasons before that at Stanford University. Olympiacos finished second in their regular season and start Top 16 play on Thursday, January 29, against Armani Jeans Milano in Milan, Italy.
