Mowbray is on the verge of becoming Middlesbrough’s new manager after holding successful talks with Gibson on Sunday.
Gibson still has alternative options, with Paul Ince, Nigel Pearson, Steve Round and Gary Megson thought to be in his thinking and an interesting offer from Fabrizio Ravanelli to succeed Gordon Strachan.
Mowbray has been out of management since an unsuccessful spell in charge at Parkhead. His assistant at Celtic, Mark Venus, will also join him on Teesside provided negotiations with the Bhoys are successful.
