BOSTON (AP) -- Paul Pierce plans to have an MRI on his left foot Monday after the second worst shooting game of his career. Pierce missed all 10 of his shots and scored one point in the Boston Celtics' 85-82 win over the Miami Heat on Sunday. "I'm just battling a couple of minor injuries to my hand and my foot," he said. "So I think that really explains my tentativeness and my off shooting today." Pierce said he sprained his right shooting hand in practice Saturday then was hit on it Sunda NBA.com
