Manchester United veteran Ryan Giggs is set to be sidelined for around a fortnight after suffering a hamstring injury in the 2-2 draw at Bolton Wanderers.
Giggs was forced from the field early on in the second half at the Reebok Stadium, with manager Sir Alex Ferguson confirming a minor setback after the final whistle.
He told ESPN: "It is a hamstring and I am afraid he will be out for a couple of weeks."
Better news about Wayne Rooney came from number two Mike Phelan, with the England striker's ankle knock nothing to worry about.
Phelan added: "Wayne Rooney had a bit of a knock. He has a little issue with his ankle, we don't know how serious.
"We will have a look in the morning but we think he will be okay for Wednesday.
"He has been playing with it for a couple of weeks now and during the game we decided he wasn't getting into the areas we wanted and he wasn't getting chances, so we had to change it."
