Clippers forward Paul George was sitting out the team's game against the Golden State Warriors after he strained his left hamstring during practice Wednesday. Los Angeles coach Doc Rivers termed the injury as ''mild'' and said the early prognosis is that it shouldn't keep the 6-foot-8 All-Star forward out of many games. Nothing violent, which you knew it wasn't bad, but he felt something and walked over to me and said, 'I think I feel something in my hamstring,''' Rivers said Friday.
