Brad Fittler admits he's unsure how NSW players will react to watching him and Greg Alexander open up on former teammate Ben Alexander dying in a car crash in 1992.
Blues players spent their day off on Wednesday taking part in the Knock-On Effect campaign which tackles the state's road deaths and serious injuries.
Fittler and Alexander, Ben's brother, spoke about the tragedy in a television commercial launched in front of the players in Bondi.
Fittler said he couldn't bring himself to watch the video, which includes images of him and Greg as pallbearers during Ben's funeral.
"I remember doing it and it was emotional doing it. I don't think I'll ever watch it," Fittler said at North Bondi Surf Life Saving Club.
