I grew up in the American (US) culture of sports. When an athlete gets an injury - in the States (MLB, NBA, NFL, NHL, etc) - injuries are disclosed quite well. normally the anatomical name and the injured site is given (ex. Achilles Tendon, patellar tendon, etc.). Also, they disclose how severe it is (ex. grade 1 strain, rupture, etc.) and a time frame of the prognosis.

Why is it in football, all these facts are so ambiguous. Do people in Europe, or specifically England, simply not care?

Edit: I graduated with a sports therapy related degree, so this aspect of sports really interests me. Also, in the US this is pretty much all public information released by the relative leagues. I have noticed, at least with Manchester United, it is always up to the Manger's decision to disclose the injury.
