Free agent Joel Przybilla is expected to meet next week with Bucks GM John Hammond and coach Scott Skiles, and the Bucks are the "front-runners" to sign him. Milwaukee currently has Drew Gooden, Larry Sanders and Ekpe Udoh capable of backing up Samuel Dalembert, but wants to add another big, physical defensive presence. The Bulls and Mavericks are also pursuing Przybilla -- each team can offer him a backup center job, though Chicago's addition of Nazr Mohammed could take them out of the running.
