Bradford boss Phil Parkinson has stressed that David Syers will not be making a return to Valley Parade.
Rumours suggested the 26 year old could be on his way back to the Bantams from Doncaster.
Rovers brought him back a week early from a successful loan at the Iron, where he scored five goals in 15 appearances. He is out of contract at the end of the season.
United are still keen to land him on a permanent basis.
