07:24 PM ET 11.20 | It looks like Darko Milicic's Boston Celtics career will end pretty quickly. Milicic is likely to return to Europe to be with his ailing mother, and he has the blessing of his head coach. "Most likely (he's gone), yeah," Rivers said. "Honestly the stuff with his family has been going on for a while. We've talked about it three or four times. It's probably 50-50, but once you get the one side working, it's always going to win out. It doesn't look like (he'll come back." The Celtics have no plans to fill Milicic's open roster spot now, but free agents such as Kenyon Martin appear to be on their radar going forward.
