In this paper we consider the following ‘Toeplitz completion’ problem: Complete the unspecified analytic Toeplitz entries of the partial block Toeplitz matrix$\begin{linenomath}A:=\begin{bmatrix} T_{\overline\psi_1}& ?\\[4pt]\T_{\overline\psi_2} \end{bmatrix}\end{linenomath}$to make A hyponormal, where ψi∈H∞ is a non-constant rational function for i=1,2.
