Students away; half in school another half in somewhere else

Here's the thing about my school. The students are very active. They are involved in everything. From playing music to sports to charity service. It is very good for their development, but there is a price to pay. They are not in class half of the time.

This then will create the chain reaction. It affect homework, performances and marks. The scariest part, I am worried about their development in my content area; English.
How do I do this? What should I do? How do I manage the left-out students?
I tried virtual classroom. But a number of them is not virtually there. At least if they are there, during break or even between matches they can sit down and flick on they smartphones; do an exercise or two. However, the downside is both things; matches and lessons need concentration. It will not work out if they are in neither.
I have yet to try something else. I need to find something that is so fun that they cannot resist. Problem is, I still don't know what it is.
