The midfielder was substituted before half-time on Saturday as Chelsea played out a goalless draw with Norwich in the Premier League.
Lampard was later seen on the bench with the leg heavily strapped but Andre Villas-Boas stated after the game that he was hopeful the injury was not too serious.
Scans have now shown that the England international only suffered a minor problem and should be available for selection again in the near future.
Revealing the extent of the damage in a statement on their official website, Chelsea indicated that Lampard would probably sit out this weekend's clash with QPR.
The Blues then face Swansea in the league on Tuesday 31st January and will hope to have Lampard back in contention.
"A scan on the injury Frank Lampard suffered during the game at Norwich on Saturday shows he has a small tear in a calf muscle," read the club statement.
"The midfielder is unlikely to feature in the FA Cup fourth-round match against Queens Park Rangers on Saturday but is expected to join up with the rest of the squad in Mallorca where they are training this week."
