Avai vs. Cuiaba (Sunday, 3.00pm)
Trailing their hosts by five points in the Serie A standings, the Auriverde arrive in Santa Catarina having taken just two points from their last four games; meanwhile, their opponents held league leaders Palmeiras last time out.
We say: Avai 1-1 Cuiaba
Cuiaba's drought cannot continue for ever, and their hosts have one of the division's worst defensive records this season, so a low-scoring draw could be on the cards at Ressacada.
Atletico GO vs. Sao Paulo (Sunday, 8.00pm)
Separated by just two points in the Serie A standings - with the visitors holding the upper hand - both teams aim to give their pursuit of a top-six place a boost with their fifth league win of the season.
We say: Atletico Goianiense 0-1 Sao Paulo
Still without an away win in the league this season, Sao Paulo can finally end their drought, on the back of a spirited cup performance in trying circumstances. Atletico-GO tend to keep things tight on home soil, though, so the margin of victory will be slim.
America Mineiro vs. Goias (Sunday, 10.00pm)
Victory would take the hosts above their visitors in the Serie A standings, amid a tightly-contested Campeonato Brasileiro.
We say: America Mineiro 1-0 Goias
As it is fair to say that neither side is prolific, a low-scoring affair is in prospect. America should edge it, as they have conceded only five goals at home this term and their opponents' glaring lack of firepower remains unresolved.
Coritiba vs. Fortaleza (Sunday, 10.00pm)
While the visitors arrive in Parana having improved their chances of Copa Libertadores progress in midweek, their hosts have lost their last four matches to sink down the Serie A standings.
We say: Coritiba 2-2 Fortaleza
Despite a decent record at Couto Pereira over the first third of the season, Coritiba have conceded 12 times in their last six league matches, and Fortaleza can capitalise on such defensive deficiencies. They have scored twice in three of their last five outings, and can do so again to secure a point on Sunday.
