Celtic are still working on deals for Steven Fletcher and Albian Ajeti but Vakoun Issouf Bayo is close to a loan exit.
Former Hibernian forward Fletcher, 33, is a free agent, while 23-year-old Ajeti is on the books at West Ham.
Parkhead manager Neil Lennon said talks are ongoing regarding both targets but said nothing has been tied up.
However, Bayo, who has struggled to make an impact at Celtic since joining in January of last year, should clinch a loan move to French club Toulouse.
