While former 2nd overall pick Nolan Patrick is sidelined with what the team calls "migraine issues", Philadelphia Flyers GM Chuck Fletcher states the team is comfortable the 21-year-old does not have a concussion. Patrick took a puck to the head during a game against the New York Islanders last season, but Fletcher says he's been checked by doctors and specialists and they don't believe he suffered a concussion.

"Nolan has a family history with migraines and has had them since minor hockey. He's on (a) medication course we are hopeful will resolve it," Fletcher told the media Thursday.

Patrick is currently considered week-to-week, but the Flyers have announced he will almost certainly miss the start of the regular season, if not longer. Patrick does have a history of injuries, from a sports hernia in 2016, to a couple of "upper-body injuries" since joining the NHL.

As for the migraine disorder, while the exact cause is rarely known and there is no cure, the illness can be managed and may subside on its own.
