Chelsea have been dealt an injury blow with news that Brazilian international midfielder Ramires will be out of action for around a month.
The 24-year-old former Benfica star damaged medial ligaments in his right knee during the 1-0 win over QPR in the FA Cup fourth round on Saturday, with Juan Mata's penalty the difference between the two sides at Loftus Road.
But Andre Villas-Boas will be counting the cost of injury to one this season's top performers at Stamford Bridge, with a club statement confirming the bad news on Sunday evening.
"Scans confirm Ramires suffered a medial ligament injury to his right knee in Saturday's game against Queens Park Rangers," said the statement.
"He is expected to be out for three to four weeks."
The former Porto boss attempted to put a positive spin on the injury post-match, admitting knee ligament injuries can often be far worse than the one his player sustained in west London, and that with treatment Ramires can make a positive return.
"It is not so bad in terms of the worst knee injuries but he'll have the MRI scan and we'll know the full extent and I think hopefully he is going to avoid an operation," AVB told reporters.
"We have to know the extent of the ligament injury and eventually with the treatment and results we have been having medically, we could be looking at a four-week period."
The injury leaves Villas-Boas with a potential selection headache ahead of the clash with Swansea tomorrow night, as Frank Lampard remains touch-and-go with a calf tear and John Obi-Mikel is still out of action with a hamstring problem.
