The club said the 55-year-old former Leeds United executive director is in a stable condition and will watch from his hospital bed on Thursday as the Black and Whites take on Wigan for a place in the Grand Final.
Hull chief executive James Clark said: “Adam is in good spirits and extremely grateful for the support and well wishes he has received, in particular the fantastic efforts of the nurses and medical staff who are working around the clock in very challenging circumstances.
“He has had a rough few days but we are looking forward to getting him back at the club in the near future after some much-needed rest and recuperation.
“It is business as usual at Hull FC. Day-to-day operations continue as normal as we continue to address the challenges faced by Covid-19 and ensuring the team have the best possible preparation for Thursday’s semi-final.”
