I believe it is a herniated disc that she has had problems with for some time. I hope she is ready also. I'm just not sure even if she is ready that she'll have a place on the team. Bars is the event the need to fill. It looks like after Nationals that Chellsie has proven she will take the #2 spot behind Nastia. She has more upgrades planned also. So for Shayla is comes down to grabbing that 3rd bars spot. Ashley Priess helped her by retiring. So in my opinion it will come down to Shayla vs. Bridget Sloan. If Bridget and Shayla are scoring equally on bars it will come down to who is doing better on Floor and Vault. Just my personal opinions.
