Gregor scored a goal and added two assists in AHL Manitoba's 8-3 win over Chicago on Sunday.
Gregor didn't make the Jets' roster out of training camp, so he'll wait for an opportunity while in the AHL. The 28-year-old forward has earned four points over the first two games of the campaign. He split his time between the AHL and NHL last year, earning 17 points in 26 regular-season games for Charlotte as well as nine points in 38 outings for the Panthers.
