[Joker's Wild]

From KHSAA: "Beginning with the 2015-2016 school year and thereafter, require that no student enrolled initially in grade (5) through grade (8) during the 2015-2016 school year or thereafter who is repeating a grade for any reason be eligible to compete in interscholastic competition involving students enrolled in grades six (6) through eight (8) while repeating a grade;"
The rule applies to anyone who is in their 1st year if a grade this year. If they hold back in the same grade next year, they will be ineligible. If this year is not their initial year in that grade, they are eligible for this year. Hold backs can play this year. It's next year when they begin to be ineligible.
