The 25 year old is in dispute with the Trotters over bonus payments regarding their promotion last season.
Speaking to the Star, Bolton chairman Ken Anderson revealed that he and David Holdsworth are in talks over full control of the club, and neogations were still ongoing causing issues over the bonus payments.
“I have made offers to both parties and I am optimistic that they will be acceptable. This lack of a resolution was the main reason why the bonuses owed to the players were not paid on time as I was reluctant to continue to solely fund the club with still no certainty of an agreement being reached with both parties." Anderson said.
“However, as I have solely funded the club with substantial amounts during these ongoing discussions over the last few months, I have agreed to continue to do so for the time being, in the hope that an agreement will be reached with both parties in the short term. Accordingly, the players will be paid the outstanding monies this week.” he added..
Proctor is already training with the Millers after passing a medical last week.
