Nieto (lower body) has been ruled out of Thursday's game against the Wild, David Pollak of the San Jose Mercury News reports. Nieto was optimistic that he'd be back in the lineup Thursday, but those hopes were dashed when he noticed a setback in his recovery Wednesday. It's not clear if it's just a minor speed bump or something that will extend his absence by multiple games, but more information regarding his condition should be available in the coming days.
