The British and Irish Lions coach Warren Gatland said the "head overruled the heart" on many of his selection decisions for the final test against Australia in Sydney.
Former Lions captain Brian O'Driscoll said he was "totally gutted" at being left out of the squad for the decisive match this Saturday.
Gatland said: "Picking this team was not easy and ultimately with several players available after recovering from injury the head overruled the heart in many selection decisions.
"Brian O'Driscoll is a great player and has had a wonderful career but for the final test in Sydney, we just felt Jamie Roberts' presence offered us something more".
