The Liverpool hitman went under the knife to correct a meniscus injury on Thursday but the Uruguayan Football Association are confident "he is not ruled out".
Suarez posted a message on Twitter later that day to thank fans for their good-will messages, and on Saturday afternoon he reiterated his determination to turn out for his country in Brazil.
