Armstrong's teammate test positive

Seeing this today on the Yahoo! Canada homepage made me wonder whether the correct news is teammates test positive or teammate tests positive. As I clicked the link to find out, I was expecting a video news story to appear. When I saw it was a text article, I expected to see a video embedded somewhere on the page. When I couldn't find a video anywhere, I wondered why that icon appears at the start of the text above. Oh, and it should be teammate tests positive.
