''The situation has been amicably resolved,'' Lee told the club's official website.
''Vinny and I have had long discussions over the past week and the upshot of these talks is that he will return to the club until the end of the season.
''He has apologised for his actions and would also like to do the same to the fans.
''We have been given assurances that he is fully committed to the task in hand and it is a big boost to us, because he is one of our most important players and would be difficult to replace.
''Players of his calibre don't come around very often and cost a lot of money to replace.''
