Bolton are hoping to finalise a deal for David Wheater before this weekend, skysports.com understands.
The Middlesbrough defender was given permission by the club to talk with Bolton earlier this month after they made their initial approach.
Despite those talks, the deal could not progress as the two clubs could not finalise their negotiations.
Now, after Wheater returned to Boro's line-up for their 4-0 win at Bristol City last weekend, Bolton are ready to push ahead and seal the deal.
The news will be a boost to Boro boss Tony Mowbray, who has conceded that the club would rather sell Wheater now than see him leave for nothing in the summer.
"In an ideal world he gets sold," said Mowbray.
"It seems a strange thing to say but otherwise he will walk away for nothing in the summer."
Boro could also be ready to let Andrew Taylor leave as he is another player out of contract in the summer.
Taylor was loaned out by former manager Gordon Strachan and he impressed hugely during a stint with Watford.
The Hornets are now keen to sign him, although Mowbray has confirmed his liking for Taylor since seeing him in action.
"I'm not too sure what is best for me now but I've got a bit of time to think about it," said Taylor.
"I know Watford have made an offer for me.
"They want me to go back down there. I loved my time down there and I love the manager down there so that is a possibility.
"But obviously Boro is something in my heart. I've been here all my career and had some good times so there is a lot to think about."
