Manchester United boss Sir Alex Ferguson says they'll be careful with the comebacks of Wayne Rooney and Patrice Evra.
Rooney has struggled with a hamstring injury since hobbling off against Wigan on 14 January, while Evra injured his ankle against Chelsea three days previously.
"They had little setbacks in training," Ferguson told MUTV. "They didn't do a lot last week, which was partly to do with the weather. They needed another three or four days' training before we could start considering them.
"I think the important thing about having injuries with the squad we've got, you don't take chances. It proves fatal. We weren't prepared to take a chance with them."
