Early years Prass was born in
Porto Alegre. After starting professionally with local
Grêmio (but never playing a senior match for them), he joined
Francana in 2000, on loan. In 2001, Prass joined
Campeonato Brasileiro Série B side
Vila Nova, becoming a starter midway through the season. He moved to
Coritiba in the
Série A the following year, and spent four seasons there. In December 2004, already an undisputed starter, Prass renewed his contract.
União Leiria In June 2005, Prass moved abroad and joined Portugal's
União de Leiria, as compatriot
Helton had left for
Porto also of the
Primeira Liga. He made his league debut on 11 September 2005 in a 0–0 home draw against
Marítimo, and retained first-choice status from that moment onwards. In the
2006–07 season, Prass only missed two league games as Leiria finished seventh and
qualified for the
UEFA Intertoto Cup, eventually being one of the competition's winners and appearing in the
UEFA Cup, being ousted by
Bayer Leverkusen in
the first round (4–5 on aggregate).
The following campaign, the team dropped down to the
second division.
Vasco da Gama After appearing in 14 matches to help União
return to the top flight in 2009, the 31-year-old Prass returned to his country and signed for
Vasco da Gama, playing in the second level for the first time in 110 years of history. Rarely missing a match, he helped the
Rio de Janeiro side
finish as champions and promote immediately, with the best defensive record in the league.
Palmeiras On 10 December 2012, Prass left Vasco and joined
Palmeiras,
recently relegated to the second tier. He helped them return to the top tier
at the first attempt; he quickly became a fan favorite due to his saves and was eventually named team
captain, as he led them to their third
Copa do Brasil title in
2015, scoring the last
penalty against rivals
Santos in a 4–3
shoot-out victory. On 3 April 2016, Prass saved
Lucca's penalty in a 1–0 home win over
Corinthians, the
Alviverdes first win over their rival at
Pacaembu for nearly 21 years. After a good start to
the season, he was sidelined with a shoulder injury until December. While his replacement
Jailson had a superb year, Prass was handed back the starting role as soon as he recovered. Midway through the
2017 campaign, however, Jailson was again named first choice over Prass. This only lasted five games as the latter was once again named starter, this time due to an injury to the former. Prass extended his contract with Palmeiras until December 2018. After Jailson's recovery and the signing of
Weverton in January of that year, he was demoted to third option on the squad. On 7 December 2019, Prass departed the club.
Ceará On 8 January 2020, at the age of 41, Prass signed a one-year deal with
Ceará. He retired at the end of
the season. ==International career==
