Ryder spent two days in an induced coma in intensive care following an attack outside Aikmans Bar in Merivale early last Thursday.
He was brought out of the coma on Saturday.
"He's been doing well over the last couple of days so just needed to complete all the testing they wanted to do in hospital and then they were happy to let him go home," Mr Klee said.
"He's still very tired and still struggling energy-wise with the effects of the concussion, but he's obviously well enough to be discharged from hospital and travel home, it's great."
Despite his speedy recovery, there was still work to be done, Mr Klee said.
"It's just amazing how quickly he's got himself back on his feet and recovering, so hopefully the rest of the recovery is as speedy, but we'll have to wait and see."
