a fractured toe -hope it doesn't effect his jumping ability -earlier in year i mentioned injuries to these high flyers are there any statistics to vertical and injuries or height weight---my son was a big leaper and went down with broken ankle and ligament damage are there any statistic on injuries if these kids started young or to height--over here in england most young kids playing all suffer knee pain because most courts are not hardwood-marcus,gordon ,randle and they are just kids---
