Petersen, a native of Waterloo, Iowa, was traded to the Philadelphia Flyers in the off-season from the Los Angeles Kings following a tough 2022-23 campaign and so they could get rid of his $5 million cap hit.
In five games for the Flyers this season, Petersen has a record of 2-2-0 along with a 3.90 goals against average and an .864 save percentage. He also has a 5-8-2 record in 15 American Hockey League games.
