Ben Askren's wife says the ex-UFC star is still fighting pneumonia ... but the battle has gotten so intense, he might now need a lung transplant.
Ben, as you know, was hospitalized earlier this month after he developed the lung ailment following a bout with staph infection. On Tuesday, Amy Askren took to her Facebook page to share a sobering update on his condition.
She revealed her hubby has been on a ventilator and extracorporeal membrane oxygenation (ECMO).
