Laughton had no points and 10 shots on goal in five games. He averaged 11:32 of ice time per game and won 44.2 percent of his faceoffs.
"It's a difficult one," Holmgren told the team's website of the decision. "He played very well, but at the end of the day it was something that we talked about and it was in the best interest of the Flyers and also Scott.
"He needs to play [and] he needs to play in all situations. He's going back to a good team and he will play a lot in all situations. He's a good young prospect and the little bit of time he had here with us was good for him and good for us."
The Flyers had to decide prior to Laughton playing in a sixth game, which would have started the first season of his entry-level contract.
Laughton, the 20th pick of the draft, was the youngest player to skate in a game this season.
