The NFL Referees Association (NFLRA) has commended the rapid response of medical staff who treated Damar Hamlin, and fully backed the suspension of the game between the Buffalo Bills and Cincinnati Bengals.
Hamlin collapsed on the field during Monday's game, with his team the Bills subsequently confirming the 24-year-old suffered a cardiac arrest.
He was given CPR on the field before being transported by ambulance to the University of Cincinnati Medical Center, where he is in a critical condition.
As stars from across the sporting world, particularly in the United States, offered their thoughts and prayers, the NFLRA lauded the swift action of the emergency responders at the Paycor Stadium.
"On behalf of the NFL officials working the Buffalo Bills vs. Cincinnati Bengals game last night we offer our thoughts and prayers for a speedy recovery for Damar Hamlin," a statement said.
"Additionally, we commend the emergency medical staff and doctors who quickly responded on the field to Damar's serious health issue."
The organisation also fully supported the decision to suspend the game.
"Like the players and coaches, our officials fully supported the suspension of this game as all attention needed to be focused on Damar's health," the statement concluded.
