Detroit Red Wings rookie Anthony Mantha scored his first NHL goal in a game at Joe Louis Arena on Thursday night against the Montreal Canadiens.

While this is a huge moment for any young player, it's especially sweet considering his grandfather and former Habs forward André Pronovost was in attendance.

The 2013 first-round draft pick from Longueuil, Que., scored Detroit's fourth goal on the power play in the closing minutes of the second period. Pronovost, who also played for the Red Wings, was overcome with emotion for his grandson.

The 21-year-old's goal stood as the game-winner as Detroit held on for a 4-3 victory over Montreal. Mantha grew up cheering for the Canadiens and it meant a lot to have his grandfather in the crowd for the big moment.

"Who knows how many more games he'll see," Mantha said.

Pronovost is a four-time Stanley Cup winner with Montreal.
