Guy Branston expects to return to Bradford when his loan spell ends at Rotherham in January.
The centre-half rejoined the Millers on a three-month deal on Friday after a previous six-year spell, but his return was soured when he was sent off on his debut in the 5-2 defeat at Bristol Rovers.
Having been a regular at Valley Parade until recently following his summer move from Torquay, Branston's exit came as a surprise, and he admits his future with the Bantams is "out of his hands".
He said: "I am going back to Bradford in January unless told otherwise. I was the Bradford captain three games ago and I want to get them promoted.
"My aim now is to go and do work at Rotherham and help them and when January comes I'll go back to Bradford. (To leave permanently) is going to have to be a situation where Bradford tell me I am not wanted and they haven't done that yet.
"I moved away from my family to sign for them so my focus is there and I just have to work hard and get back into the side and impress the Rotherham manager (Andy Scott) and then hopefully impress my manager at Bradford (Phil Parkinson) so he can make a decision. It's out of my hands."
