The defender entered the fray with 20 minutes to run in the 4-0 victory.
Hurzeler later said: “It’s the Brighton way to develop young players.
"They do a great job in the Academy and we have an unbelievable under-21 coach in Shannon Ruth. Ruairi is very mature for his age, a great personality and deserved to be in the squad.
"I’m happy he had his chance today and he took it impressively. It will be interesting to see how he develops.”
