Manager Terry Brown insists a busy week on the training field lies ahead for his AFC Wimbledon players after seeing the Dons concede 11 goals in their two matches.
A 5-1 defeat at Bradford on Saturday followed their 6-2 loss at Burton Albion four days before and, to complete another bad day for the club, debutant left-back Curtis Haynes-Brown was taken to hospital with a neck injury after an accidental clash with City winger Zavon Hines in the second half.
Play was held up for seven minutes while the player received treatment before being carried off the field on a stretcher.
"He has gone to hospital for a precautionary scan on his neck," said Brown."He was unconscious on the field so we didn't want to take any risks.
"It was an eventful day for the young lad. It was his debut and he managed to score an own goal, but in a terrible defensive display I thought he was excellent. He can hold his head up high."
Brown added: "We have been working all week with the centre-halves, but we didn't deal with the ball over the back four and if you can't deal with that sort of ball you are in trouble."
Bradford boss Phil Parkinson explained that watching Wimbledon's defeat at Burton on Tuesday night enabled him to formulate a plan to expose their weaknesses.
All the goals came in the first half, with Nahki Wells, Andrew Davies, Rory McArdle and James Hanson on target for City. Byron Harrison pulled a goal back for the Dons to make it 3-1.
Parkinson said: "We understood what was required. Wimbledon had suffered a heavy defeat and we knew they would come here committed, but also if a team has conceded goals like they did at Burton we knew there would be vulnerability in the side. We needed to exploit that, which we did."
