(CNN) -- Fears that England star Wayne Rooney will miss the World Cup have abated with news that his injury is minor, but key Spanish player Cesc Fabregas has been ruled out for the rest of the season.
Rooney limped off with an ankle problem in Manchester United's European Champions League defeat by Bayern Munich on Tuesday, causing concern that soccer's showpiece event would be deprived of one of the planet's best players.
But English club United announced on Thursday that the 24-year-old striker may be able to return to action this season, following a scan on his injury.
"We're pleased to report that Wayne has not suffered a fracture. The scan revealed only minor ligament damage," a club spokesman told United's official Web site.
While United did not say how long Rooney would be sidelined, manager Alex Ferguson is expected to reveal more details at Friday's press conference ahead of the important weekend match against English title rivals Chelsea.
However, the UK Press Association reported that Rooney is likely to be out for between two and four weeks, meaning he will miss the Chelsea match and the second leg of the quarterfinal against German side Bayern.
Fabregas, however, has been told results of his scan have revealed a crack in his fibula, sustained during English club Arsenal's 2-2 draw with Barcelona in their quarterfinal clash on Wednesday.
The midfielder was an injury doubt before the game and hobbled around the field for the final five minutes after scoring his side's late equaliser from the penalty spot. He left the ground on crutches and later told reporters he feared he had "broken" something.
Arsenal confirmed on their Web site: "Cesc Fabregas has suffered a small crack in his right fibula as a result of the collision with Barcelona defender Carles Puyol.
"As a consequence, Cesc will miss the remainder of the domestic campaign as he will be out of action for at least six weeks."
Fabregas will now face a race to be fit for the World Cup finals in South Africa, that begin on June 11. Spain's opening fixture is against Switzerland on June 16.
Arsenal also lost Russia forward Andrei Arshavin and France defender William Gallas to calf injuries, while Brazil midfielder Denilson and defender Gael Clichy are also doubtful.
Arsenal manager Arsene Wenger told the club's Web site: "William [Gallas] had a recurrence of his calf strain. That is at least three weeks. The next one is Arshavin - calf strain, three weeks.
"At the moment, we are like an army who have come back from a big battle. Who will be available for the next one? I have to wait 24 hours more."
