Leeds have doubts over 20-goal striker Luciano Becchio for the trip to Crystal Palace.
The Argentinian missed Friday night's goalless draw with Reading due to a hamstring strain and may again be unavailable against the Eagles.
Billy Paynter and Max Gradel lined up in attack last time out, but with Davide Somma, Ross McCormack and Sanchez Watt waiting in the wings, Grayson could opt to freshen things up.
The manager's only other problem is the absence of winger Lloyd Sam, who will again be sidelined with a knee injury.
Leeds dropped out of the play-off places after the weekend's fixtures, but Grayson is concentrating only on his side.
"We'll look at Palace and hopefully doing a job there," he said. "We can only affect the games we are involved in. We have to look after ourselves first and then see how the others have done."
