Updated: Shane del Rosario in Critical Condition After Suffering Cardiac Arrest

---

UFC heavyweight Shane del Rosario suffered cardiac arrest on Tuesday morning and remains in critical condition at Hoag Memorial Hospital Presbyterian in Newport Beach, Calif.

ESPN's Josh Gross, a former Sherdog.com editor, is reporting that del Rosario is on life support and a final decision by the fighter's family is expected Friday a.m. whether or not to continue with machine assistance.

“Shane del Rosario had a catastrophic cardiovascular collapse at home on Tuesday morning,” Jason House, del Rosario’s manager, said in a statement released to Sherdog.com. “He was brought to the hospital in full cardiac arrest. He was resuscitated in the emergency room back to a stable heart rhythm and blood pressure. He is currently in the coronary care unit critically ill. Our prayers are with him and his family.”

According to Erik Apple, del Rosario was found at home by his roommate, UFC flyweight Ian McCall. McCall called 911 and administered CPR to del Rosario before he was taken to the hospital. Apple says that del Rosario had no prior health issues with his heart.

Apple told Sherdog.com on Wednesday that positive strides were seen, but due to recent reports Thursday evening it seems del Rosario's condition has worsened.

The 30-year-old del Rosario was scheduled to make his third Octagon appearance against Carlos Augusto Filho at UFC 168, but the bout was canceled when both men suffered injuries leading up to their Dec. 28 clash.

After beginning his professional MMA career with 11 straight victories -- including three with Strikeforce -- Del Rosario suffered a herniated disc in an April 2011 car accident. He returned to make his Octagon debut against Stipe Miocic at UFC 146, where he lost via second-round TKO. He was knocked out by Pat Barry in his last outing at “The Ultimate Fighter 16” finale.
