  The class of quasi-graphic matroids, recently introduced by Geelen, Gerards,
and Whittle, is minor closed and contains both the class of lifted-graphic
matroids and the class of frame matroids, each of which generalises the class
of graphic matroids. In this paper, we prove that the matroids $U_{3,7}$ and
$U_{4,7}$ are the only $9$-connected excluded minors for the class of
quasi-graphic matroids.
