It was a tough blow for the Philadelphia Flyers during training camp as general manager Chuck Fletcher announced that Nolan Patrick wasn't cleared to participate. 

Originally labeled as just an "upper body injury" it was later revealed that Patrick had actually been diagnosed with a migraine disorder. 

Patrick has been around the team but there hasn't been any updates regarding his availability. 

NHL insider Bob McKenzie gave an update regarding Patrick on the latest edition of TSN's "Insider Trading". 

"He’s been listed as ‘week-to-week- so there is no official timeline to when he might be back, but the good news is, his condition has been improving he’s not 100 per cent by any stretch of the imagination. But on Tuesday for example, he skated 30 minutes with the Philadelphia Flyers, in a non-contact jersey obviously. And the good news too, as the Flyers headed west in Vancouver, Edmonton and Calgary they took Patrick along with them. He’s going to continue his rehab and his conditioning and the feeling is that this is like his training camp, and that maybe sometime in the next three weeks he might be back playing games and that could include a conditioning stint in the American Hockey League. But he’s trending in the right direction."
