A source close to the situation has told us that he'll announce for UCLA.
Sidney will be UCLA's sixth commitment for the class of 2009.
In fact, UCLA doesn't currently have a scholaship available to accomodate Sidney. One will have to open up by the time he's on scholarship this summer.
UCLA's recruiting class is currently ranked #4 in the country, but the addition of the nation's #5-ranked player would give UCLA a good case for the #1 class.
