BOSTON (WHDH) — Celtics coach Doc Rivers made a statement Monday after former Celtic Jason Collins became the first active player in a major American sport to be openly gay:

"I am extremely happy and proud of Jason Collins. He’s a pro’s pro. He is the consummate professional and he is one of my favorite “team” players I have ever coached. If you have learned anything from Jackie Robinson, it is that teammates are always the first to accept. It will be society who has to learn tolerance. One of my favorite sayings is, 'I am who I am, are whom we are, can be what I want to be its not up to you, it’s just me being me.'"
