The news of Boucher's withdrawal from the Proteas' tour to England was confirmed on Tuesday by the SA Cricket magazine on their Twitter page.
Boucher, 35, who had hinted this could be his final campaign before retirement, was hit in the face when a bail ricocheted off the stumps after Gemaal Hussain was bowled by Imran Tahir during the first day of the Proteas' tour opener against English county Somerset at Taunton.
Boucher, as would be expected for leg-spinner Tahir, was standing up to the stumps, but he was wearing a cap rather than a helmet.
After treatment on the field, Boucher was helped off with blood coming from his left eye and taken to hospital.
His place behind the stumps was filled by AB de Villiers, who has kept wicket in international matches for South Africa.
