On this day in rugby league history, a Panthers great is born, royalty at the SCG, Darren Lockyer's 300th and a classic Sam Kasiano tackle.
Panthers hooker and coach Royce Simmons was born. Simmons made his debut for the club in 1980 and was made captain in 1983. He won his first NSW jersey in 1984, also taking out the Dally M Centre of the Year and Captain of the Year awards that season.
In 1986 he became the first Penrith player to represent Australia, going on to represent his state and country 10 times each.
After retiring following his memorable two-try performance in the 1991 grand final, he coached Penrith from 1994 to 2001, taking the Panthers to the finals in 1997 and 2000.
