Luton boss Rob Edwards says the on-pitch cardiac arrest suffered by Tom Lockyer at Bournemouth last weekend was the scariest moment of his life.
Luton captain Lockyer, 29, collapsed in the second half and was taken to hospital, with the match abandoned.
He was discharged on Thursday having had an Implantable Cardioverter Defibrillator (ICD) device fitted.
"It was the scariest moment I have ever had, never mind in football," said Edwards.
"The medical guys were incredible. It was a crazy pressurised situation with the world watching and they got every decision bang on.
