The 30-year old has been ineligable to play for the club since his short term contract ran out on the 8th January but now a deal has been struck meaning that the former AC Milan and Bordeaux man will be available for the club's game against Portsmouth tommorow.
Ba joined Bolton from Milan in September and has been a key figure in getting the club to the Carling Cup Semi Finals. Middlesbrough did show an interest in taking the player to the North East but now both club and player have reached an agreement for the player to remain in Lancashire.
