Either way it kind of sucks that she's the only girl that couldn't make it to the training
It's certainly possible she had surgery because she mentioned an injury and didn't say what she did to treat it so it's possible
Honestly I think it's probably more likely that she did have surgery.
Either she had what she's had in the past and it's just taking time off
Or she had a freak accident and injured herself that way
Or she had what she had in the past and decided to have surgery
I really doubt it was a freak accident because she probably would have just said that
And it's kind of strange that she couldn't make it on this trip when she's had the last four months off from everything
So it's kind of more likely that she got frustrated with constantly having this nagging recurring injury and decided to get surgery
Also it's quite possible that they could do a procedure like this at a doctor's office especially if it's a high-tech arthroscopic procedure. She might have went to a special Center rather than a hospital so the whole covid thing might not have did not much of a factor in scheduling
Anyway my money's on that she had some sort of surgery to deal with tendonitis
