Aston Villa striker Darren Bent is set to make a loan move to Brighton in the next 48 hours, according to Sky sources.
Juan Cala wants to find 'another club ASAP' and believes Cardiff have acted without respect towards him.
The Sky Bet Championship club, whose manager Brian McDermott worked with the Mali international at Reading, have the option of a permanent deal in the summer.
McDermott actually scouted Kebe at Reading and later worked with him as a manager, winning promotion to the Premier League in 2012.
"Jimmy is a player that I scouted from France in 2006. He has fantastic pace, he is a real team player, and he made and scored goals for us in the Championship and the Premier League. I'm delighted he's come on board and I'm really looking forward to working with him again," McDermott said.
Kebe joined Palace in the summer but has failed to make an impact and has been restricted to six appearances this season.
