Omar Daley has played his last City game after switching places with Rotherham winger Kevin Ellison.
The Jamaican winger, City's longest-serving player, has completed a move to the promotion-chasing Millers this afternoon on a three-month emergency loan.
In return, the Bantams have picked up the battle-hardened Ellison for the same period.
Ellison, 31, trained with his new team for the first time this morning and is set to go straight into the squad against Wycombe on Saturday.
It will be the third time that he has signed for Peter Taylor after playing for him at Leicester and Hull.
Taylor said: "I know how exciting at times Omar can be but I know Kevin really well and he can play a couple of positions.
"He's left footed, wants to cross the ball and can also score a goal."
Neither player will be involved against their parent club when City host Rotherham next month.
