With Jon Fortune and Andy Gray out for the rest of the season, Addicks boss Phil Parkinson has acted quickly to get Wolves centre-half Ward and Leeds striker Kandol into the squad for tomorrow's game at Burnley.
Manager Parkinson said: "After losing Jon for the season and with both Mark and Graeme extremely doubtful for the Burnley game on Saturday, we had to move quickly.
"They are three key players, and we needed some defensive options, so I'm delighted to get Darren, who will give us a great physical presence.
"The loss of Andy has given us more problems, and Tresor is very hungry to play so we're pleased he is on board."
