Tigers legend Benji Marshall choked back tears after his team's 25-16 win over the Knights on Friday night while chatting to Fox Sports sideline reporter Megan Barnard.
The 33-year-old star fought through a heartbreaking week, losing his grandfather on Wednesday.
"It's been pretty tough," a teary Marshall said. "He wanted to play this week. The funeral's tomorrow (Saturday), I'm just going to get back to the family.
"I'm just glad I do what I do for a living, he was my biggest fan..."
Marshall revealed his grandfather told him "you have to play" before passing away.
