Mills knows his chances of a first-team recall at City are limited and it has been suggested he would be willing to head back to Elland Road in an effort to help them stave off relegation to League One.
However, Stuart Pearce has confirmed the deal cannot go through because Mills is yet to recover from the shin splits which forced him to curtail a loan stint at Hull earlier in the season.
"Unfortunately, Danny is not fit at the moment," said Pearce. "He has still to get over the stress fracture of his shin.
"Until we get him fully fit, we can't make any decision about him. Danny is happy with that and understands the situation."
Og sånn ble det med den saken....[xx(]
