"My family and close friends have known since June of the direction I wanted my life to go. Those were the toughest conversations that I have ever had but with the ultimate support I knew I was making the right decision," Martin wrote in the advertisement.
Martin's most notable stretch came with the Sacramento Kings, where he played five full seasons. He finished 2008-09 with a career-high average of 24.6 points.
In 2010, he was traded at the deadline from the Kings to the Rockets in a deal that included Tracy McGrady. Martin spent the rest of that season with Houston.
