[...] Golden State officials, of course, are eager for the rookie center to play with their NBA Development League affiliate, the Santa Cruz Warriors, this weekend. "We haven't even seen Jones play basketball yet," head coach Steve Kerr said before Friday night's game against the Lakers at Staples Center. Jones, 21, tore his right pectoral muscle while weight lifting 12 days before going 30th overall to the Warriors in June's NBA draft. During non-contact work the past month, he impressed coaches with his defensive awareness and developing midrange game. At 7-foot, 245 pounds with a 7-2 wingspan, he has prototypical size and strength to patrol the paint in the NBA. Forward Julius Randle (hip pointer) and guard Nick Young (sprained toe, left foot) are out Friday against the Warriors, Lakers head coach Luke Walton said.
