An acetabular prosthesis assembly can include an acetabular cup and a first liner. The acetabular cup can have an outer surface, an inner surface and an upper rim extending between the outer surface and the inner surface. The acetabular cup can have a cup connection portion including a groove formed on an upper face of the upper rim. The first liner can have an outer cup engaging surface and a liner connection portion that extends from a flange of the first liner. The liner connection portion can have a finger that is received by the groove formed on the upper face of the acetabular cup that selectively couples the liner connection portion with the cup connection portion in an assembled position.
