Hi, Yes they can as I have done it and it does not damage the Astro Turf. It does need to be pegged in as it make it difficult to play football when the goals are moving around and you have to keep putting them back when someone scores.

I got these for my 7 year old and he play with a hard ball, seem OK and standing the test of time so far (9 month) I'm sure if older children were to play with them they might suffer eventually but have been a good buy
