Here is a link to many websites where you can watch live sports. Might be laggy sometimes, but at least it’s free.
First you have to make sure you have an ad-blocker extension installed on your browser. I recommend uBlock Origin. It is compatible with Google Chrome, Firefox, Edge and Opera.
Here is the link to it. https://ublockorigin.com/
Now that you have an ad-blocker you can safely go to the list of live sports websites below.
