Miami Dolphins owner Stephen Ross has decided not to discipline general manager Jeff Ireland for asking Dez Bryant, during a predraft interview, whether Bryant's mother was a prostitute. ``I have looked into the matter of Jeff Ireland and the questions asked of former Oklahoma State receiver Dez Bryant, and I have spoken to many people in and outside our organization who were directly and indirectly involved,'' Ross said in a statement. ``Jeff Ireland has apologized personally and publicly to Dez Bryant. We are going to take a hard look at our interview practices and we will make improvements that will allow us to get the important information we need about players in whom we are making a major investment, but without being insensitive. ``Jeff Ireland is a man of great capability and integrity, and he is well deserving of my continued confidence. I consider the matter closed.''
