Oakland Raiders running back Darren McFadden sat out his third straight practice with a sore hamstring and is almost certain to miss Sunday's game against San Diego. Michael Bush, off to a slow start after missing the first two games with a broken left thumb, handled the majority of reps in practice Thursday and will likely start against the Chargers. McFadden's absence would be a blow to Oakland's sputtering offense. The former first-round draft pick is tied for third in the NFL with 392 yards rushing, 35 more than he had all last year. It's also the best start by an Oakland running back since LaMont Jordan had 424 yards after four games in 2007. Source: ESPN
