Yes, I pulled the port hex end cap when I replaced that impeller and found a couple of bits but nothing serious.Probably from multiple failed impellers over the years.
the why part will probably always be a mystery. Who knows, maybe they somehow got pushed upstream when you jammed the mud in, or higher pressure from restricted flow crammed them into the tubes enough to restrict flow
have you pulled the cap on the other side to this extent?
