Lockyer, who has had an implantable cardioverter-defibrillator (ICD) fitted, had previously stated he would be “at peace” with the prospect of not playing again following his collapse.
But he had always stressed a desire to return to the pitch, including a wish for “just one more” Wales appearance to add to his 16 caps, having spent time with Craig Bellamy’s squad in September.
And, under the guidance of the same specialists who oversaw Denmark’s Christian Eriksen’s comeback after his own cardiac arrest, Edwards said Lockyer had been closing in on the all-clear for a full return.
“It is [remarkable], and that’s down to him as a person, the fact that everything has gone very, very well,” said Edwards, a former Wales international himself.
“He’s in really good condition and every specialist and all the medical people looking at him have been really pleased with every step of the process.
“No cutting corners with this because obviously it’s so important, but I don’t think there is any reason why he won’t play.”
