We report an independent Doppler confirmation of the TESS planet candidateorbiting an F-type main sequence star TOI-1408 located 140 pc away. We presenta set of radial velocities obtained with a high-resolution fiber-opticspectrograph FFOREST mounted at the SAO RAS 6-m telescope (BTA-6). Ourself-consistent analysis of these Doppler data and TESS photometry suggests agrazing transit such that the planet obscures its host star by only a portionof the visible disc. Because of this degeneracy, the radius of TOI-1408.01appears ill-determined with lower limit about $\sim$1 R$_{\rm Jup}$,significantly larger than in the current TESS solution. We also derive theplanet 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 significantorbital eccentricity of $0.259\pm0.026$. Our solution may suggest the planet islikely to experience a high tidal eccentricity migration at the stage ofintense orbital rounding, or may indicate possible presence of other unseencompanions in the system, yet to be detected.
