Nolan Patrick was not listed on the Philadelphia Flyers' training camp roster on Monday.

Selected No. 2 overall in the 2017 draft, Patrick has yet to play this season due to a migraine disorder, last playing on April 2, 2019 - 468 days ago.

Patrick skated in a non-contact sessions during the season and general manager Chuck Fletcher said in January he expected to see him return at some point this season.

“Our focus is on getting him ready for the 2020-21 season," Fletcher said Monday. "We want to be prudent and prioritize his health and safety in the long run. We have a short run way here before we jump right into playoff hockey.”

Patrick, 21, scored 13 goals and posted 31 points in 72 games last season. He has 26 goals and 61 points in 145 games with the team.
