The possibility of an anomalous coupling between the top and charm quarks and the gluon field is explored in a model-independent way using an effective Lagrangian that is gauge invariant under a nonlinear realization of [Formula presented]. Even for the current 200 [Formula presented] of integrated luminosity at the Fermilab Tevatron, the new physics scale that strongly modifies the coupling of [Formula presented] must be larger than about 2.5 TeV if no signal is found within a [Formula presented] confidence limit. For 1 [Formula presented] of data, this constraint can be pushed up to 3.8 TeV.
