Cameron Munster says he let his teammates down on the weekend after being sent to the sin bin.
The Storm five-eighth produced a professional foul early in the first half of their match against the Eels and spent ten minutes off the field, with Parramatta scoring two tries in that time.
"I let the boys down I guess, [it was] a bit of a mind blank and a bit of a brain explosion for myself, coming around the 15 minute mark," he said.
"I felt pretty bad. It was a pretty tough game for us, and a big high to get the week off, but also Cameron Smith playing his 356th game for us as well.
"I thought I let him down. I think they scored ten points in the time I was off. It was a crucial part of the game for us. Hopefully next week it doesn’t happen again."
Munster said he was able to re-focus after returning to the field.
"I had to obviously get on with the next job," he said.
"I obviously stuffed up. I knew it was probably going to be a decision I was going to get 10 in the bin. I knew I needed to pull my head in a little bit and obviously not make that mistake again, and put the team under pressure."
He compared the intensity of Saturday's match to that of the 2016 grand final.
"It felt like a grand final for us, to be honest," he said.
"For me, the speed, the physicality of the game was everything I had last year against the Sharks."
Munster said some of the younger players were anxious before the game but is hopeful they'll keep things in check for the bigger games to come.
"I was looking at some of the boys in the sheds before the game and they were biting their nails, some of them were quite nervous," he said.
"But [players like] Josh Addo-Carr and Curtis Scott have been playing great all year, just hopefully they don't get overawed by the occasion next week."
