Virtual homomorphisms from mapping class groups to lattices in $SO(n,1)$

Using results of Sampson and Carlson-Toledo, I will prove that every homomomorphism from a finite index subgroup of the mapping of a surface of genus at least $3$ to a cocompact lattice in $SO(n,1)$ virtually factors through a surface group.
