Manchester United and England striker Wayne Rooney is set for several weeks on the sidelines after suffering a hamstring injury in the 1-0 win at home to Wigan Athletic.
Rooney scored the only goal of the game in the first minute at Old Trafford, but limped out of the action a mere seven minutes later.
Red Devils boss Sir Alex Ferguson said after the hard-fought victory: "Wayne scored a good goal, but he will be out for about three weeks now. Hopefully it is no longer."
Meanwhile, Ferguson heaped praise of United centre-half Nemanja Vidic and the visiting Latics for their parts in a tense tussle.
The Scot added: "Nemanja was magnificent. It was the best performance you are likely to see from a natural centre-half.
"His reading of the game is excellent and he is as tough as nails. He was absolutely superb.
"I thought Wigan were absolutely fantastic, we have had to dig really deep.
"It was a test of our character in the last half hour because Wigan gave an absolutely brilliant performance."
