The 28-year-old was handed a late call-up to the first team by coach Lee Radford, and played his part in a narrow 7-6 defeat to Warrington.
“It was a great feeling to make my debut and not only get that first game under my belt, but play in front of such vocal and passionate support,” Michaels told his club’s official website.
“I had been told before joining the club that the fans here were a cut above the rest, and so far they have lived up to expectation.
“Unfortunately, pre-season didn’t go the way I expected with the clean out of my knee, so when Radders told me I was playing, I was over the moon.
“Even though we missed out on the result there are plenty of positives to take from that game. The lads played for each other just as a team should play, if we do that in every game then we will win more games without a doubt.”
He added, “There is a healthy competition here between every player from senior to youth, for me it’s about making sure I’m a level ahead of them to secure my position in the squad.
“We have some class players in wing and centre position but, I know I can bring more energy to the squad and now it’s my time to prove.”
“I feel very privileged to have signed for this club, I want to make supporters and former players proud for this special year,” he said.
“If we can win something big this season it would make the milestone even more exceptional.”
