Mike Miller said he's feeling the effects of two blows to the head on Miami's current road trip.

However, he refused to admit it affected his performance, including his miss on a potential tying three-pointer just ahead of the final buzzer against the Celtics on Sunday.

Miller suffered a concussion last Friday night in Detroit and took a shot from Kevin Garnett in Boston.

"It's not why I missed," Miller said. "I'm a little woozy from it still but it is not why I missed."
