The 49ers will unveil their new uniforms during a draft party, but they won't actually hit the field until the 2010 season. This is from the NFL in regard to the procedure for changing uniforms: "A club must give written notice and details thereof to the League by March 1 of the year prior to the year in which it wishes to change and must submit the final design and physical samples of the uniforms to the League office for approval by November 1 of that same year."
