Lindy says there are no side effects to his exercise. The test is the only things stopping him from playing. Possibly his baseline was on a great day "Like you got 100% on the test and ur a 80% student". he needs to get closer to his first baseline test, taken two years ago before he is cleared 2 play.
He doesn't need to wait another week. The Sabre doc's r looking at him when he gets back to see if they missed anything. That would scare me. What if he's too messed up in his head, even though he can skate like crazy and get no headaches, but his memory, language, attention, reading, planning, visual-spatial analysis, and problem-solving functions are dysfunctional?
