You don?t need to take any player on a yellow off at half time, eg had it been Mowatt, no need.

But, if a player is known to sometimes be something of a walking red card, you should sub that player, Molumby in this case.

Of course Molumby is mostly to blame, but, I think Mason can?t get away without some criticism.

And, if Johnston wasn?t injured (which I know nothing about at this moment), it?s criminal to sub him, in my opinion.
