Haynes-Brown, who was making his debut for the Dons during their 5-1 defeat at the hands of the Bantams last Saturday, was stretchered off halfway through the second half of the game at the Coral Windows Stadium.
The defender picked up a nasty-looking neck injury after challenging with Zavon Hines for a Kyel Reid cross just past the hour mark.
Thankfully though, despite initial concerns, it does appear that Haynes-Brown's injury isn't as bad as first feared.
He was kept in overnight at Bradford Royal Infirmary after the game for observation before being allowed to return south on Sunday.
Haynes-Brown did suffer a concussion in the incident but x-rays have confirmed no fractures to his neck or cheekbone.
Bradford City Football Club would like to take this opportunity wish Curtis a speedy recovery.
