The 19 year old complete his stay with the club at the weekend and was originally heading back for the south coast on Monday.
But the boss is pleased that he has been able to extend the player’s stay.
Adams told the club's official website: "We thought we had lost Damien, which was a shame, as I believe he adds something for us.
"We had put everything in place for him to return to Plymouth and as far as we were concerned he had left the club.
"However, Plymouth have now kindly agreed to loan him to us for another month on the terms of the original deal, which I am delighted about."
