I make it 6 Championship sides losing at H/T:
Blackburn (1-2), Brentford (0-3), Ispwich (0-1), Bristol City (1-0), MK Dons (0-!), and Nottingham Forest (1-2)
A lot of the rest are level:
Hull, Birmingham, Reading, Huddersfield, Burnley, Brighton, Wolves, Fulham, and Bolton.
Looking good for upsets!
