Chelsea midfielder Frank Lampard has a torn right thigh muscle and will be out "for a few weeks", according to the club.
Lampard limped out of the Blues' 4-4 draw with Aston Villa on Boxing Day during the first half and underwent a scan on Thursday which revealed the extent of the injury.
A statement released by Chelsea read: "Scans today have revealed a tear in Frank Lampard's right thigh.
"The tear is not in the same leg that Frank injured earlier this season.
"He will begin his rehabilitation immediately and we hope to have him back playing within a few weeks.''
