In British English, you can "do sport". In American English you can "play sports".
A typical mistake Spanish speakers make is using the verb practise for sports:
I love practising sport. This should be: I love sport.
I usually practise sport every evening. This should be: I usually do sport every evening.
However, in American English you can use the verb practise or practice (as it is spelt there) to mean "to train": The team is practicing for tomorrow's competition.
