Manchester United defender Patrice Evra has been ruled out for three weeks with a foot injury.
The France international was replaced midway through the second half in Sunday's 3-0 win over Chelsea at Old Trafford.
Evra was making his comeback following a four-game ban for his part in a post-match fracas in a game against the Blues last season.
However, the left-back will now definitely miss Wednesday's Premier League visit of Wigan Athletic, plus the forthcoming trips to Bolton Wanderers and West Bromwich Albion, after scans confirmed ligament damage in his foot.
Speaking before his diagnosis, Evra had said: "It's something I've had since the Romania match with France in October.
"My foot tensed up after the cross, but for the moment I'm just thinking of the victory."
Meanwhile, United boss Sir Alex Ferguson has received a boost with the news that scans on Rio Ferdinand's back problem have revealed no major problem.
The England defender was expected to return following a four-game absence against Chelsea, but suffered a second back spasm on the morning of the game and was not risked.
He could now return in time to face Tottenham in the fourth round of the FA Cup on January 24.
