Cant be a real help without knowing the uni rules but one thing from when I was at uni.
If you are doing 3/4 of a timetable you can be classed as ft or part time. Check out the rules at his uni, he may be able to drop down to part time which means he will get another semester of funding.
Another thing to look in to is APEL, if there is something he can do at an FE college or in the community that will give him some skills that can be used to APEL a unit / module he wanted to do this semester.
Psychology seems to me it would go well with sports coaching.
Some unis have a work placement module or a community service module that can be done by working/volunteering - it won't count towards 'core' modules but could add another module to his electives.
I'm thinking something like volunteering to coach a school team or working with the scouts. At one of my unis this was very open and lots of EU students went to be language assistants in local schools.
Things can sometimes be flexible with other units/modules, I did some second year units in my first year in my second subject.
He needs to start looking at where he wants to be next year and then work backwards from that.
Can he take units out of a different school/faculty?
It is not the end of the world, his degree may contain units/modules that are not standard, but might make him more employable in the long run.
