Leeds had missed him, dropping from the fringes of the top-half to a lower mid-table position.
He had an immediate impact after being brought on from the bench, setting up Souleymane Doukara for the only goal of the game.
Wood is a key player for the Whites, the only player in the squad who can play the target man role with any guarantee of quality.
He could start on Tuesday against Brentford, which would only be welcome.
