Does this pitch look like it would hurt my arm?

Im 14 and found this pitch on the internet called the football change and wanted to throw it but wondered if it will hurt my arm. Here a picture of it http://www.beabetterhitter.com/text/fundamentals/footballchange/footballchange.html
Please help me

It looks like a straight change only with straight fingers, it might hurt if u put to much effort into getting it over the plate. Being that your so young why not try a three finger change?
