extracurricular or sports on cv?

Hey people, so I was wondering what you guys would put in priority on a cv. I'm currently building my cv for London spring weeks and I was asking myself if I should replace the sports segment on it to add space for an extra extracurricular. For a bit of context I was a basketball and football player at a second division teams academy, now while that might look good on a cv since I heard banks like athletes. I thought it might also be worth it to replace it with some more relevant and intellectual extracurriculars like a huge model united nations I participated it for instance. Also mind you so far in my cv there only is 1 extracurricular but its quite a significant one.
