However, the TIU said the suspension has been reimposed "following consideration of additional evidence", adding that no more appeals will be accepted.
"The effect of the provisional suspension is that Mr Souza is ineligible to compete in or attend any sanctioned event organised or recognised by the governing bodies of the sport," the TIU said in a statement http://www.tennisintegrityunit.com/media-releases/brazilian-tennis-player-joao-souza-provisionally-suspended-independent-anti-corruption-hearing-officer.
Souza, who turned professional in 2006, has never won an ATP Tour title as he has spent the majority of his career on the Challenger circuit.
The 30-year-old reached his career-high singles ranking of number 69 in 2015.
More tennis players were disciplined for violations of anti-corruption rules in 2018 than in any other year since the creation of the TIU 10 years ago.
Eight lifetime bans were imposed last year, most notably to Italian former world number 49 Daniele Bracciali for match-fixing and facilitating betting.
