Gregor was recalled from AHL Charlotte on Tuesday.
Gregor has produced 11 goals, 17 points and a plus-7 rating over 25 appearances in the minors this season. He also has one goal and two helpers across 24 outings with Florida in 2025-26. The Panthers are dealing with several injuries up front, so Gregor could play with the big club against Seattle on Tuesday for the first time since Jan. 8 in Montreal.
