DANNY ADAMS today left Town by mutual consent.
The 31-year-old left-back has reached agreement on the remainder of his Galpharm contract, which was to expire in summer.
Adams was told 10 days ago that he was free to look for another club and he hasn't played since - teenager Joe Skarz taking over the League I slot at No3.
"When Danny came to see me about a new contract I was honest with him and told him I couldn't guarantee terms for next season," said Jackson today.
"He has been an excellent servant since he joined us, but I felt it was in the best interests of everybody to sort something out quickly and Danny agreed with that.
"I don't know whether he's got anything fixed up, but we wish him well."
Former Town player Lee Fowler has been listed by Burton Albion.
