Meanwhile, Valladolid's inevitable relegation could be confirmed, with the visitors languishing at the foot of the league standings.
Match preview
Betis are competing on two fronts at this late stage of the season after they recently progressed to their first-ever European semi-final.
Los Verdiblancos set up a Conference League semi-final clash against Fiorentina after they backed up a 2-0 first-leg victory over Jagiellonia Bialystok with a 1-1 draw in last week's away fixture.
Manuel Pellegrini's side followed their European success with a commanding performance in Monday's La Liga away clash against struggling Girona, as Johnny Cardoso, Antony and Isco all scored first-half goals to seal a 3-1 victory, representing their third win in four away league matches (D1).
Having collected 51 points from 32 games, Los Verdiblancos are sitting in sixth spot and just one point adrift of fifth-placed Villarreal, knowing a top-five finish would be enough to secure them Champions League football for the first time in 20 years.
Betis will now return to the familiar surroundings of the Benito Villamarin, where they have won four of their previous five home league matches, although their only defeat in that period took place in their most recent home outing against Villarreal.
They are now at risk of losing back-to-back home legaue matches for the first time since 2023, but they can take confidence from the fact they have won their previous two game against Valladolid at the Benito Villamarin.
Valladolid will travel to Andalusia in a despondent mood after losing 12 of their previous 13 league games, including each of their last six matches.
They showed an element of fighting spirit in Sunday's home clash against Osasuna, although goals from Raul Moro and Mamadou Sylla could not stop the Pucela from falling to a 3-2 defeat, meaning the league's worst defence has now conceded 76 goals in 32 games.
As a result, Valladolid's immediate return to the second tier could be confirmed this week, with the basement side sitting 16 points adrift of safety with just 18 points left to play for.
While the writing may be on the wall, Thursday's visitors will still want to end their 11-game losing league run on the road by claiming their first La Liga away victory since beating Alaves 3-2 in October.
The basement side may be able to draw some inspiration from the fact their most recent win took place in January's reverse fixture against Betis, which saw them claim a narrow 1-0 victory thanks to Kike Perez's second-half effort.
If they are to complete a league double over Betis, the Pucela will have to end their seven-game winless run in away La Liga away games against Andalusian clubs (D4, L3).
