Osasuna are currently 12th in the La Liga table, two points and one position behind Cadiz, who have impressed in their first campaign at this level for 15 years.
Osasuna finished 10th in La Liga last season on their return to this level of football, and Jagoba Arrasate's side have already secured at least one more campaign in Spain's top flight.
Indeed, a record of 10 wins, 11 draws and 14 defeats from 35 matches has left Los Rojillos in 12th position in the table on 41 points, 11 points clear of the relegation zone.
Osasuna will be looking up the division rather than down at this stage as they are only three points behind 10th-placed Celta Vigo at the time of writing, although there is a chance that the picture could have changed by the time that this match kicks off.
Arrasate's side saw a three-game winning run come to an end against Celta on April 25 before losing at Real Madrid on May 1, but they will enter this match off the back of a 2-2 draw away to Athletic Bilbao on Saturday, with Ante Budimir scoring a leveller for the visitors in the 89th minute of the contest.
Cadiz, meanwhile, will enter Tuesday's clash off the back of a 2-1 victory over struggling Huesca on Saturday, and Alvaro Cervera's side have now only lost one of their last seven league games, with the defeat in question occurring against the champions Real Madrid.
The promoted club have picked up seven points from their last three matches against Real Valladolid, Granada and Huesca, meanwhile, and will fancy their chances of securing another positive result in this game.
Cadiz are operating at this level of football for the first time since the 2005-06 season, and they have secured back-to-back campaigns in the top flight for the first time since 1992-93.
Cervera's team are currently 11th in the table but are only three points off eighth-placed Athletic Bilbao on the same number of games, and it would be some story if they were to finish in the top half of the division.
El Submarino Amarillo have also been impressive on their travels this term, picking up 23 points from 17 matches, recording six victories in the process.
Osasuna possible starting lineup:
Herrera; Vidal, Aridane, D Garcia, Cruz; Torres, Moncayola, Torro, Brasanac, Kike; Budimir
Cadiz possible starting lineup:
Ledesma; Carcelen, Fali, Lopez, Akapo; Izquierdo, Jonsson, Mari, Malbasic; Lozano, Negredo
We say: Osasuna 1-1 Cadiz
There is not an awful lot between these two sides in terms of quality, and we are expecting a well-matched game on Tuesday evening. Osasuna ran out 2-0 winners in the reverse match earlier this season, but Cadiz are in strong form, and we fancy the visitors to secure a share of the spoils.
