MFA Boston has an impression of the full triptych:

The artist is Yasuji, and date given by MFA is 1887. MFA doesn't give the wrestler names, but the one at right appears to be "若嶌", so I guess that would be Wakashima Kyūzaburō 若嶌久三郎.
It looks like you were on the right track in terms of the Emperor being in audience, although the man seen on your sheet appears to be another member of his retinue.
