But that leads to the question of whether Weir can come back after this setback. Well, for one, we aren't talking about an ACL tear, it seems, so that should eliminate fears about it being "career-ending." That said, it becomes a question of whether this injury will continue to give him problems and how he is going to be able to train as a result. Injuries like this are often question marks, and I think the biggest question mark is whether getting back to full strength is possible.
And let's step a bit further back. What Weir has been capable of since he announced his comeback has been, by all accounts, tremendous. All of his triples are back in play plus a quad toe that seems to be pretty legitimate. His performance at Finlandia to start the season was a great start, but the issues at Rostelecom are most definitely a setback.
A lot will depend on the state of his ACL. But Weir has done a lot of the grunt work already to get his jumps back, which means that, even if he decides to take the rest of the competition season off so that he can train at his (and his ACL's) own pace, he's not back to square one.
So my verdict? Weir fans, it's not the end of the world. Weir non-fans, don't count him out.
