It is another short delivery on middle. AB de Villiers goes back and tries to pull it out of the ground again. This time though he only gets a top edge which goes high in the air. Johnson at deep mid-wicket settles himself under it and takes a skier. A good catch by the Aussie. End of a quickfire partnership.

Now they check for the LBW and the impact is outside off. The on-field call has to be overturned.
