Huddersfield were another second-tier side to go as they were beaten 2-1 at home by Notts County, whose near neighbours Nottingham Forest were also on the wrong end of an upset as they were beaten 4-3 by Walsall, despite equalising in the 90th minute, thanks to a Tom Bradshaw hat-trick for the visitors.
