Luke Walton probably won’t make his exhibition debut in Tuesday’s game against the Utah Jazz at the Honda Center in Anaheim. But he might do so in Thursday’s exhibition against the Golden State Warriors in San Diego. If not then, then it might be in the next night’s rematch between the Lakers and the Warriors in Ontario. Walton has been sidelined since the first week of training camp by a strained right hamstring, which could be related to the back injury that limited him to 29 games last season. He said his back feels fine finally.
