We present the discovery of TOI-1994b, a low-mass brown dwarf transiting a hot subgiant star on a moderately eccentric orbit. TOI-1994 has an effective temperature of ${7700}_{-410}^{+720}$K, V magnitude of 10.51 mag and log(g) of ${3.982}_{-0.065}^{+0.067}$. The brown dwarf has a mass of ${22.1}_{-2.5}^{+2.6}$M_J, a period of 4.034 days, an eccentricity of ${0.341}_{-0.059}^{+0.054}$, and a radius of ${1.220}_{-0.071}^{+0.082}$R_J. TOI-1994b is more eccentric than other transiting brown dwarfs with similar masses and periods. The population of low-mass brown dwarfs may have properties similar to planetary systems if they were formed in the same way, but the short orbital period and high eccentricity of TOI-1994b may contrast this theory. An evolved host provides a valuable opportunity to understand the influence stellar evolution has on the substellar companion's fundamental properties. With precise age, mass, and radius, the global analysis and characterization of TOI-1994b augments the small number of transiting brown dwarfs and allows the testing of substellar evolution models.
