Manchester United have announced Wayne Rooney has suffered "minor ligament damage" but the club have not disclosed how long the striker will be missing for as a result of the ankle injury suffered against Bayern Munich.
Tuesday witnessed worrying scenes for club and country in Munich as Rooney turned over on his ankle in injury time of the club's 2-1 defeat and left the Allianz Arena on crutches and in a protective boot.
Estimations of Rooney's likely absence have ranged from two to six weeks, but Sir Alex Ferguson will deliver his verdict on the recpueration period needed in his weekly press conference on Friday.
For now, following scans, the club have only confirmed that Rooney, who has scored 34 goals in all competitions this season, has not suffered a break.
"We're pleased to report that Wayne has not suffered a fracture," a club spokesman said. "The scan revealed only minor ligament damage."
It is expected that Rooney's injury will not impact on his chances of featuring at the World Cup finals, but he will certainly miss an important game against Chelsea at the weekend.
Rooney is also expected to sit out the second leg of the Champions League quarter-final against Bayern and possibly the first leg of the semi-final, should United qualify.
