Clicking on the above link will lead you to a page where you can take an on line course [takes about 20 mins] . Just choose which category you fall into ;player/coach etc. You can even print out a personalised certificate at the end to show off with!
There are loads of other resources there also.
Please take time out to be aware of the signs/symptoms and the return to play protocols.
Note: We do not have time out 'HIA' [head injury assessment] at our level of rugby
Thank You
