The months of struggling to get a game for Ajax were finally over, and the flying Dutchman was back doing what he loves most - playing on a big stage in front of appreciative fans.
But for the £2million signing, that ecstasy was quickly replaced by agony - literally - as Boerrigter's jets were cooled courtesy of a heavy challenge in the first half of his debut against Ross County.
Even as he limped off, the murmurs were already beginning in the stands.
The reputation as a player with a history of injuries is one he rails against, pointing out that throughout his senior career he has regularly played 30 games a season and that it took a broken bone in his back to finally make him give in to the pain and accept he needed time out of the game.
So, it's understandable the last thing he wanted - or needed - when he got the chance to start afresh at Celtic was an early injury which forced him out of action until last midweek's Champions League play-off victory over Shakhter Karagandy.
In hindsight, the 26-year-old acknowledges his enthusiasm to get going may have been foolhardy as he had arrived with an ankle knock from his final appearance with Ajax.
But even more hurtful is the suggestion he is not up to the heavy, physical nature of the game in this country.
Boerrigter bristles at the notion he may need to prove to the Celtic fans - or any opponent - he is strong enough, both physically and mentally, to deal with the rigours and demands being placed on him in Scotland.
He said: "I don't have to prove anything. If you see my record of where I have been, you will see that in every league I have played more than 30 games (a season).
"Physically, I have always been well, except for the first year I was at Ajax when I broke a bone in my back. That was the first serious injury I ever had."
Boerrigter is honest enough to concede the time he took to recover from that serious injury blunted his fitness and, ultimately, that cost him his place in Frank de Boer's side.
Now that he is back up and running, he aims to rack up the appearances for Celtic - including, he hopes, in the Champions League - to leave no-one in any doubt he is made of the right stuff.
Boerrigter realises first impressions can be lasting, and was desperate to make a positive one when he first pulled on the Hoops.
Having to come off after just half an hour was not part of the plan.
But Boerrigter explained: "It was just bad luck that I got an injury in my first game. That was really frustrating because, before I came to the club, I already had a little injury.
"I got a kick on an ankle when I was playing for Ajax against Osasuna. But after two weeks here, I played in the game against Ross County and I got the same kind of kick.
"I kind of twisted it as well, and it hurt like hell. So we decided it was better for me to come off and get treatment.
"But now I feel good again and I am looking forward to playing in the big games."
