  The modified gravity (MOG) theory is applied to the gravitational wave binary
merger GW190814 to demonstrate that the modified Tolman-Oppenheimer-Volkoff
equation for a neutron star can produce a mass $M=2.6 -2.7 M_\odot$, allowing
for the binary secondary component to be identified as a heavy neutron star in
the hypothesized mass gap $2.5 - 5 M_\odot$.
