FILE - In this Aug. 18, 2012, file photo, San Francisco 49ers running back LaMichael James (23) is carted off the field after being injured against the Houston Texans in the fourth quarter of an NFL preseason football game in Houston. What at first looked like at least one _ if not two _ long-term injuries for San Francisco's newest running backs in Saturday's 20-9 preseason loss at the Houston Texans suddenly doesn't seem so bad.
