The other day, I played Valen and whilst using Fezglitch, I managed to plough into my own prone player

As he was already prone, we made a straight armour roll, which he survived. However, from here, we were unsure whether that player could take a turn as he:
a) wasn't knocked over by the ball and chain
b) didn't have his armour broken
We decided that he could take a turn. was this correct?
