It is indeed the right shoulder.
Two reporters this morning stated that sources told them that if this game meant anything Hurts would be able to play. I guess there is a strategic advantage to forcing Dallas to prepare for a different offense (no RPOs, or very few of them, fewer deep shots) under Minshew this week as well. If you assume the Eagles' chances of winning their last three games are roughly 30% at Dallas, 60% home vs. NO, and 60% home vs NYG (if they both need the win), their chances of earning the #1 seed without help are roughly 89% now. Getting help is pretty unlikely, you would need Dallas (in its other 2 games), Minnesota, and SF all to lose at least once, which is roughly 20%.
Hurts would improve the Eagles' winning chances to roughly 50%/80%/70% (basing these round numbers off of money line odds before the injury), meaning having Hurts in all three games takes them from 91% to 97+%.
Protecting Hurts was obviously worth more than a 6% increase in their chances of getting the #1 seed to them.
