Ryan Howard has indeed been diagnosed with a ruptured Achilles tendon and will undergo offseason surgery.
Howard suffered the injury on the final play of Friday night's crushing NLDS Game 5 loss to the Cardinals. He's likely to miss the entire first half of the 2012 season, and could even be out the entire year. It's a major blow to the Phillies, who owe him $125 million over the next five seasons.

Yeah, he will miss most of next year. That's a tough injury, especially for a big man. I don't know enough about the lower leg mechanics of hitting a baseball, but I think the ability to drive your hips off your back leg is pretty darned important, and this requires locking your heel. Hopefully he has a full recover.
Imagine is Howard had crushed that ball over the fence? What is the ruling if he cannot circle the bases?
