Andrew Bynum suffered a strained left Achilles tendon in the third quarter of tonight’s game against the Minnesota Timberwolves. He was not expected to return to the game, which the Lakers led almost from start to finish. He will be re-evaluated Saturday. Bynum suffered significant injuries to each of his knees in the last two seasons. He had made it through 2009-10 without hurting his knees. He had scored 11 points and grabbed five rebounds before he left the game. The Lakers led the Timberwolves, 78-68, after three quarters.
