  An analysis is performed to constrain the $W'$ boson production using the
measurement of the s-channel single top quark production cross section. Both
phenomenological and statistical approaches are examined and results are
presented. In the best case, $W'$ bosons that interact only to the right-handed
fermions are excluded below 1390 GeV. To our knowledge, it is the first time
that the measured cross section of the s-channel single top quark production
from the colliders is used to rule out part of the phase space of the $W'$
boson.
