The Bucks announced Friday that forward Ekpe Udoh will be sidelined for 4-to-6 weeks after undergoing arthroscopic surgery on his right knee.
Udoh, 26, did not play during Milwaukee's first two preseason games because of knee soreness, and the surgery will keep him out for the remainder of the exhibition schedule. His initial recovery timeline has him missing the Bucks' first 4-to-11 regular season games.
New Bucks coach Larry Drew opened the preseason with a starting frontline of Larry Sanders, Ersan Ilyasova and Caron Butler, and that trio figures to command the majority of the minutes in the early going, once Ilyasova recovers from an ankle injury. Reserves John Henson, Zaza Pachulia and Miroslav Raduljica are also on hand during Udoh's absence.
Last season, Udoh averaged 4.3 points, 3.3 rebounds and 1.1 block in 17.3 minutes per game over 76 appearances. Acquired by Milwaukee in a 2012 trade with Golden State, the 2010 lottery pick will make $4.5 million in 2013-14, the fourth year of his rookie deal. Milwaukee opens the regular season against New York at Madison Square Garden on Oct. 30.
