These articles should be "news" based content, and 90% about Diaz v McGregor, if you're struggling they can be 100% rewritten from existing articles on other websites, and be ANY UFC news, BUT they must make perfect English sense and be interesting to read and use images and media.
... The articles cannot be 100% copy pasted from sites, these will be rejected and you won't be paid for 100% copied work, however, I understand if you've taken an article and added to it or rewritten it to make it unique. This is encouraged.
A strong command of English is very important for this job, and a full understanding of Wordpress CMS, knowledge of sports will help a lot.
