A tubular tool body carried at the end of a drilling rig top drive is received within a drill string being used as a landing string to position casing in a wellbore. External threads on the tool body can be mated with the box threads of the drill string to secure the top drive and drill string together for simultaneous drill string movement and fluid circulation. An annular seal carried about the tool body engages and seals with the internal wall of the drill pipe to prevent drilling fluid leakage when the tool body is received within the drill pipe without thread engagement. The tool has an internal check valve that opens to allow back flow of drilling fluid that may be displaced from the drill pipe as the pipe is lowered into the well. The check valve prevents standing fluid in the top drive from spilling onto the rig floor when the tool is withdrawn from the drill string.
