And the young tight head had a pivotal role to play in the final few moments as Gloucester faced a scrum in their own 22 while hanging on to a slender 27-24 advantage.
The scrum was reset once as both packs out everything into one last effort but, when push came to shove, Knight forced Alex Waller to buckle to secure a penalty which Freddie Burns hammered into touch to seal the win.
It was a massive moment for the former England U20 international as he told the club website after the game.
"It was my Premiership debut which meant a lot and it was a great game to be involved in. It was tight at the end but we got the win, which makes it even better.
"They're known for having a big scrum and it would have been nice to have got one against (Soane) Tonga'uiha. But (Alex) Waller is still a good prop and it was hard work."
All the pressure was on Gloucester in the final few moments. Had a penalty been conceded at that scrum, the Saints would have had an easy penalty to draw the game.
There was a slight delay before the two packs engaged so what was said amongst the Gloucester forwards?
"I remember Alex Brown saying that, if any scrum mattered, then this was it. And he was right. We won the penalty and edged the game."
"It was in the back of my mind as we packed down but I just had to focus on doing my job and making sure we won the scrum."
Freddie Burns duly hoofed the ball into touch to end proceedings and, as a proud Gloucester boy, Knight admitted that the moment was a special one.
"It's difficult to put into words really. I was really happy, just jumping about. It means everything.
"Freddie went to boot it into the Shed and the crowd were counting the seconds down. I was just hoping he didn't scuff it! But he's too good for that."
"The ball went into touch, the crowd erupted and it was relief first and then excitement."
