The NRL has today paid tribute to commentator Darrell Eastlake, who has passed away aged 75.

"Darrell was an iconic Rugby League caller, renowned for his commentary of State of Origin," NRL CEO Todd Greenberg said.

"For a long time, his voice personified State of Origin.

"His calls were always colourful, larger than life, and he oozed passion through every tackle or big moment.

"Darrell will always be part of the rich history of State of Origin and he played an important role in the growth of the contest as a whole."
