The move seems to indicate Sandin will stick with the Marlies at least at the start of the season, similar to 2017 first-round pick Timothy Liljegren. The 18-year-old Swede, who finished last season with the Sault Ste. Marie Greyhounds of the OHL, is eligible to play in the AHL because he was on loan from his Swedish club Riga.
If Sandin doesn’t stick with the Marlies it’s expected he will play for Riga, which competes in the top league in Sweden.
Nielsen, 21, is set to play in his third season with the Marlies. He had six goals and 26 points in 65 AHL games last season.
Der-Arguchintsev, 18, was a third-round pick by the Maple Leafs in June. The Moskova, Russia, native returns for this third season with the Petes, where he had 12 goals and 51 points last season.
