Celtic have signed Moroccan left-back Badr El-Kaddouri on loan from Dynamo Kiev.
A club spokesman confirmed the 30-year-old had joined until January, although Celtic have the option to buy the player.
Celtic manager Neil Lennon has been looking for a left-back since Emilio Izaguirre broke his ankle earlier in August.
The Morocco international joined Kiev in 2002 and made 26 first-team appearances in 2010-11.
Lennon had made an enquiry about Manchester City's Wayne Bridge and been linked with a move for West Ham defender Herita Ilunga.
Honduras international Izaguirre was ruled out for between four and six months after suffering the injury during Celtic's victory at Aberdeen on August 7.
