It kept Perfetti out of the final two games of the trip - a win over the New York Rangers and a loss to the New York Islanders - as he was reassessed and the team waited on the final results.
Those results will have the forward out for a significant amount of time.
At the time of his injury, Perfetti was third among NHL rookies in points with 30, trailing only Anaheim's Mason McTavish (32), and Seattle's Matty Beniers (42).
For a significant chunk of the season, Perfetti was also near the top - or at the top - of the rookie list in assists.
Now, Bowness will have to continue the line juggling to cover for Perfetti, who had developed great chemistry with the two centres he played the most with - Mark Scheifele and Pierre-Luc Dubois.
"You keep juggling. You have no choice," said Bowness. "There are line shuffles that you're forced to make, and that's one of them. You have to move guys in and out, see if it works, give it a chance, and go from there. It's coaching in the NHL today. You never know when that injury is going to come and you have to be ready to adjust."
The 30 points Perfetti has racked up this season are the sixth most on the Jets, and that production was great to see from the 10th overall selection in the 2020 NHL Draft. He had missed the end of the 2021-22 season due to an upper-body injury as well, and was back to 100 percent at the start of camp.
Oddly enough, the injury that ended his year last season occurred on February 17, 2022.
And then, 367 days later, another upper-body injury will see him miss significant time.
He's worked through that adversity before, and no doubt he'll put the work in to try and get back as quickly as possible.
