Awoniyi underwent two rounds of abdominal surgery this week after being rushed to the hospital on Monday following an accident during the team's match against Leicester City on Sunday.
The Nigeria international was placed in an induced coma for the second round of surgery to stabilize his heart rate.
Nuno expressed relief that the surgery was successful, saying, "He went to surgery and everything went well, thank God."
Awoniyi is currently being closely monitored and is recovering, with Nuno and the team keeping a close eye on his progress.
Nuno acknowledged the challenges the team has faced, saying, "It has been very difficult on us and on everybody."
