Andrew Luck should be back on American soil sometime next week following an extended stay in Europe, where he was seeking treatment for his ailing shoulder. A new report from Stephen Holder of the Indianapolis Star indicates there is some positive news behind his decision to remain overseas a bit longer than anticipated. Holder also doesn’t discount the possibility that Luck has already begun throwing the ball. He responded to a question on Twitter about Luck throwing once he returns by writing, “Presumably. But here’s some food for thought: What if he’s ALREADY doing some throwing? The optimism we’re getting from sources has to be based on something. And it *could* be that.” Obviously, it would be tremendous news for Luck and the Colts if he were already able to throw without pain or swelling in his shoulder.
