Suppose Kal-El, son of Jor-El, living under the assume identity Clark Kent, decides to spend some time as a professional athlete.
Suppose he reveals his true identity. Obviously most professional athletes protest that this is unfair and actually mostly pointless because he can outperform entire teams of athletes to amazing fits and set new unbeatable records.
Clark Kent, however, does not relent. He insists that he should have the same right to participate in sports and (for example) earn a college scholarship if he wants to play on a sport team for his college team.
Is there anything in the current law which would allow a college to deny him the right to make a certain sport essentially irrelevant by playing it?
While I am asking the question in jest, I also ask that you, please, support your answers with links (or at least quotes) of the relevant rules, laws and regulations.
For the purposes of this question, let's assume that the question of Kal-El's citizenship has been legally settled based on the fact that his adopted parents adopted him legally. Let's assume the courts have settled this issue, at least for this one individual.
