According to reports, Bruno will vote at each results show via video link but won't be present on the Saturday-performance show.
They are hoping he'll be in the studio for the semi-final and final, and potentially a couple more episodes later in the series if restrictions ease in LA.
They aren't expected to replace him for shows he isn't at.
