We prove the existence of weak solutions of the equations of unsteady motion of an incompressible fluid with shear-dependent viscosity in a cylinder , where denotes a bounded domain. Under the assumption that the extra stress tensor possesses a -structure with , we are able to construct a weak solution with . Our approach is based on the Lipschitz truncation method, which is new in this context.
