  We investigate indirect constraints on the top partner within the minimal
fermionic top partner model. By performing a global fit of the latest Higgs
data, $B_s \to \mu^+\mu^-$ measurements and the electroweak precision
observables we find that the top partner with the mass up to 830 GeV is
excluded at $2\sigma$ level. Our bound on the top partner mass is much stronger
than the bounds obtained from the direct searches at the LHC. Under the current
constraints the fine-tuning measure is less than 9% and the branching ratio of
$T \to tZ$ is bounded between 14% and 25%. We also find that precise
measurements of Higgs couplings at 240 GeV TLEP will constrain the top partner
mass in multi-TeV region.
