Ailing Golden State Warriors coach Steve Kerr says he won't be on the sidelines for Game 4 on Monday against the Portland Trail Blazers because of symptoms stemming from back surgery. Kerr stayed behind at the team hotel for Saturday night's Game 3 at Portland's Moda Center. Assistant Mike Brown took over and the Warriors overcame a 17-point first-half deficit to win 119-113 and go up 3-0 in the first-round series.
