The Flyers Nolan Patrick, drafted second overall in 2017, has suffered another setback in what was supposed to be his breakout year.

Patrick has been considered week-to-week during training camp, but the Flyers announced that he has been diagnosed with migraine disorder and will certainly miss the start of the season. While the exact cause of the disorder is rarely known and there is no cure, the illness can be managed and subside on its own. Patrick does have a history of injuries, from a sports hernia in 2016, to at least a couple of the dreaded "upper body injuries."
