Manchester United duo Jonny Evans and Anderson have been ruled out for the next three weeks due to injury.
Evans and Anderson both suffered ankle injuries during United's 4-2 win over Derby County in the second leg of the Carling Cup semi-final on Tuesday night.
Anderson was stretchered from the pitch at the final whistle and there were fears that the Brazilian midfielder had suffered a serious injury.
However, following scans on the problem, United manager Sir Alex Ferguson has confirmed Anderson is out for the next three weeks.
"We sent Anderson for a scan and there's no break," said Ferguson. "But there was some ligament damage. We think he'll be out for three weeks."
Portuguese winger Nani also picked up a knock against Derby and is out for a week, while Evans faces a similar absence to Anderson.
Ferguson added: "Nani suffered a groin injury and he'll be out for a week. Jonny Evans will be out for three weeks."
The injuries leave Ferguson with a depleted squad for Saturday's FA Cup fourth-round tie against Tottenham Hotpsur, with several more first-team regulars on the sidelines.
He continued: "The ones who are out are Rio Ferdinand, Anderson, Nani, Rafael, Patrice Evra, Wayne Rooney, Jonny Evans and Ji-sung Park [hamstring injury]."
