He was held out of the first 51 games of the ensuing season, but still somehow managed to look better than ever upon his return, scoring in his first game back and finishing with an eye-popping 26 points (10 goals, 16 assists) over the final 31 games of the 2016-17 season.
Now, less than two years after the injury, Huberdeau is coming off the best season of his career.
"I think after the injury to the Achilles it's never easy to come back from that," Huberdeau said after cleaning out his locker at BB&T Center in April. "It wasn't easy on the body this year, but it was fine. I'm glad I kind of had a chance to do it. This summer is going to be really big to come back and hit the next level and come back next year and do better."
In his first full season since the injury, Huberdeau set new career highs in goals (27), assists (42) and points (69) while also suiting up in all 82 games. His 69 points placed him in a tie for 37th in the league and his 42 assists were tied for the 10th-most in franchise history.
A staple of the top-six, Huberdeau was a key contributor at both 5-on-5 and on the power play for the Panthers. He ranked third on the team in points (50) and second in goals (20) at even strength, while also sitting behind only linemate Vincent Trocheck in power-play points with 19.
Huberdeau also skated 19:12 per game - the highest average ice time of his career.
"It was a good season," Huberdeau said. "Best season point wise, personally. Overall, I thought we didn't have the start that we wanted. We always come back to the start. It's huge to have a good start so at the end you have some points in the bank. We didn't so we tried to catch up the whole last half of the season and the team in front of us didn't give us a chance."
With five years remaining on the six-year deal he inked in September of 2016, Huberdeau is only now just beginning to enter his prime. He'll be 25 years old when the puck drops on the 2018-19 season and will play a big role in helping the Panthers get back into the playoffs.
How big a role? Well, Florida was 28-12-3 when he recorded at least one point this season.
"We'll probably have a similar group that we had this year, some young guys coming in," Huberdeau said. "We just need to feel comfortable with each other and come back and be confident, get a good start and get some wins."
