The issue about whether the Miami Heat might cast aside Mike Miller under the league's one-time amnesty policy might already have been decided by the 3-point specialist himself. Miller confirmed Thursday to the Sun Sentinel that he underwent surgery for a sports hernia this week and could be sidelined for up to two months. "That's just my luck right now," he said when reached by phone. "I've just got terrible luck. I don't know what's going on." Already on the way back from offseason thumb and shoulder surgeries, Miller recently said he finally felt that he had turned the corner on his injury issues. But he also said he felt a lingering soreness. That's when he went to see Heat physician Harlan Selesnick. Even amid the NBA lockout, players were allowed to consult with teams' medical staffs.
