Zach Miller underwent emergency surgery on Sunday in an effort to save his injured left leg.

Miller dislocated his knee in the third quarter of Sunday's game against the Saints. Sources told Mortensen that Miller's dislocated knee is considered "more significant" than a regular dislocation, which is a serious injury.

Vascular surgeons were called in to repair Miller's leg, which includes grafting tissue from the other leg to repair the damaged artery.
