Connor Goldson came through a 13-hour open-heart operation during the night.
He spent Sunday night in the ICU after doctors finished the job.
Goldson wrote a short post just after midnight to say he's holding steady.
This was the second time in recent months he has needed significant operation.
The defender has now left hospital and is resting at his house with his family nearby.
Clinicians have him under observation as he recovers.
