You can go ahead and uncross your fingers now. It didn’t work:
Richards is anticipated to miss 6 to 9 months. The club has placed him on the 60-day DL.

Obviously, Richards is done for the season. Less obviously, Richards might even miss the first month or two of the 2015, though there is hope that he could actually be good to go come training camp. According to Jeff Passan, that seems likely:
If there's a silver lining, Angels were told Richards tore his patellar tendon in best spot possible, should be ready for spring training.

The bigger question, to which there is no current answer, is what the impact this injury will have on his career? Cursory searches of the ol’ internet tubes haven’t turned up any examples of other MLB starting pitchers who have suffered the same injury. That’s probably good, but it might also be bad. Who knows. I don’t. I just want to cry, mostly.
