  We report an independent Doppler confirmation of the TESS planet candidate
orbiting an F-type main sequence star TOI-1408 located 140 pc away. We present
a set of radial velocities obtained with a high-resolution fiber-optic
spectrograph FFOREST mounted at the SAO RAS 6-m telescope (BTA-6). Our
self-consistent analysis of these Doppler data and TESS photometry suggests a
grazing transit such that the planet obscures its host star by only a portion
of the visible disc. Because of this degeneracy, the radius of TOI-1408.01
appears ill-determined with lower limit about $\sim$1 R$_{\rm Jup}$,
significantly larger than in the current TESS solution. We also derive the
planet mass of $1.69\pm0.20$~$M_{\rm Jup}$ and the orbital period $\sim4.425$
days, thus making this object a typical hot Jupiter, but with a significant
orbital eccentricity of $0.259\pm0.026$. Our solution may suggest the planet is
likely to experience a high tidal eccentricity migration at the stage of
intense orbital rounding, or may indicate possible presence of other unseen
companions in the system, yet to be detected.
