She was very obviously still using both arms when she was up 5-2 and when she was tied 5-5.
She very clearly injured (reinjured?) Her shoulder during the match as evidenced by (1) her obvious pain at the conclusion of the match (2) the ice bag on her shoulder on the stand and (3) her statement to the other wrestler after the match that she hurt her arm posting on it near the end of the match.

I have no idea if she was 100 % for the match but is disingenuous to claim she wrestled the match "1 armed".
