Miller said: "I messed up. I made a bad call. (There were) a lot of ways to handle the situation, I handled it wrong and I'm paying a price for it. I messed up a big opportunity and I'm hurting on the inside. My heart is bleeding right now - I hurt my family, my friends, my team, my supporters. But, I'm owning up to it. I'm going to deal with it. I'm going to correct it. I'm going to come back better and I'm humbled by the experience."
