EAST RUTHERFORD, N.J. — Kobe Bryant scored only two points on 1-for-7 shooting before suffering an as yet to be determined leg injury in the closing seconds of the first half tonight. He charged into the New Jersey Nets’ Devin Harris and landed awkwardly. He was tended to by Lakers medical personnel during a 20-second timeout and then headed for the locker room with the Lakers ahead by two points with 52.2 seconds left in the half.
