David Wheater could turn out for Middlesbrough's Championship clash at Bristol City on Saturday with his future still to be resolved.
Although manager Tony Mowbray confirmed the defender, who is out of contract in the summer is set to leave the Riverside, the club have yet to agree a fee with Bolton.
It is believed that the Premier League club have already agreed personal terms with the player and Wheater is keen to make the switch to the Reebok, but the deal now hangs in the balance.
The Teessiders are reportedly demanding a £4million fee for the 23-year-old which they are determined to hold out for.
Wheater has returned to training with Boro and now could be in the frame for the weekend trip to Ashton Gate.
Assistant boss Mark Venus told the club's official website: "David is still here. He trained with us on Monday and Tuesday.
"Right now, he is still a Middlesbrough player, he is contracted to the club and, if he is still here at the weekend, then there's every chance he will be playing.
"Of course, we would like the situation to be resolved - and it will be by January 31 - but I know David has always done his all for the football club and that's all we can ask."
