Former Penn State All-American, four-time Super Bowl winner, and onetime Detroit Lions general manager Matt Millen has received a Christmas miracle.

Matthew H. Millen, Matt Millen’s son, posted on Facebook that his father underwent a “wildly successful” heart transplant early Monday morning. Matt Millen had been waiting for a new heart since being diagnosed with a rare condition called amyloidosis last year, which was causing heart failure to the point of needing a transplant.

“We are praising God this morning that dad’s heart transplant was “wildly successful” last night,” Matthew H. Millen wrote.

“What a wonderful Christmas gift! The doctors said the heart was “a perfect fit” and everything went smoothly during the surgery. THANK YOU to everyone who was praying!”

Peter King of NBC also reported the good news, writing:"

Millen is out of surgery. He’ll be in recovery until late this afternoon. In a text from the hospital, Millen’s wife Pat said: “Doctors said the heart was a perfect match and he is doing well. The surgery went smoothly.”

Millen had been calling college football games for Big Ten Network as recently as two months ago before he took time away from the booth to prepare for the eventual heart transplant.
