Anthony Davis left in the third quarter after bruising his lower back on a painful fall during the Los Angeles Lakers' sixth straight victory, 117-87 over the New York Knicks on Tuesday night. Davis bruised his sacrum — the bottom part of his spine above the tailbone — when he attempted to block Julius Randle's driving shot. LeBron James scored 31 points and Kentavious Caldwell-Pope added 15, but the Lakers (30-7) didn't exactly celebrate becoming the second team to win 30 games this season.
