After fitting in some light throws Wednesday, Schaub (elbow) will do so again Monday to discover his level of health, Albert Breer of NFL Network reports. As a result, Schaub's sore right elbow should keep him sidelined during Thursday's preseason finale versus the Seahawks. After three underwhelming exhibitions in which he completed just 51.1 percent (24-for-47) of his passes, tendinitis emerged as the culprit, with rest the recommended remedy. The Raiders expect him to reach the requisite level of health to start in the regular season opener on Sept. 7 at the Jets, but rookie Derek Carr (ribs) is waiting in the wings in case Schaub is deemed inactive.
