"They were eating and some seafood got caught in his throat and he started choking. Sam raced straight over and grabbed him and started putting his body weight on him to try and get it out.
"He was helping him for about 30 to 40 seconds and instead of spitting it out he ended up swallowing it, but if Sam hadn't have helped it could have been bad.
"I'm telling you Sam is a hero."
It was added that Burgess was not the only Souths member to rush to the choking staff member's aid, but it was the cross-code England international who ultimately saved his life by clearing his airway.
"He saved his life. Another 30 seconds and it could have gone either way," the witness added.
