Carroll, on a season-long loan with the Hammers from Liverpool, sustained the injury in the second half of Wednesday's 1-0 defeat at Manchester United and was absent from the squad for Saturday's London derby against Chelsea.
England international Carroll has endured a difficult time at Upton Park, scoring just once in 10 games for Allardyce's side and missing a month of action at the start of the campaign due to a hamstring injury.
"It's pretty severe. We didn't expect it to be quite as severe," Allardyce told BBC Sport. "It's going to be about six to eight weeks. It's a blow for us and Andy."
