"I do expect him to play again this year, but that's just my guess," Flyers general manager Chuck Fletcher said Tuesday. "He's been skating harder. Skated again today. Getting his heart rate up higher. I think he's feeling a bit better."

Patrick, who has a history of migraines, has not played this season. The forward notified the Flyers in June that he was experiencing headaches that came on randomly, but doctors said they aren't believed to be concussion-related.

The No. 2 pick in the 2017 NHL Draft, Patrick had 31 points (13 goals, 18 assists) in 72 games last season. He has 61 points (26 goals, 35 assists) in 145 NHL games.

"I can tell you from the on- and off-ice workouts he's doing, he is progressing, but there certainly isn't any clear path as to which way this will go," Fletcher said. "He's skating at a higher level. I watched him today. His skill level is still there, shooting the puck great. I guess the important thing is when we get to the point where he is feeling well enough to take that next step. He's been working hard at his conditioning."

The Flyers (24-16-6) play at the St. Louis Blues on Wednesday (8 p.m. ET, NBCSN, TVAS).
