Mallorca's awful run continued as another defeat at home to Athletic Bilbao last weekend means they have now not won in 14 games in all competitions and have taken just two points from the last 33 available in the league.
Joaquin Caparros also has selection worries for the trip to the Benito Villamarin as Pedro Geromel is suspended so Anderson Conceição is expected to return alongside Jose Nunes.
Ximo Navarro could also come back in at right-back as a defensive move with Emilio Nsue moving forward into midfield into his more natural position.
Mallorca played much better than they have in recent weeks against Athletic, but their inability to score goals again cost them, as indeed did their slack defending when Aritz Aduriz scored the only goal of the game from a simple looping ball into the area.
Betis will undoubtedly put the Islanders' defence under an even stiffer test and neither side has shown anything in recent weeks to suggest this will be anything other than a routine Betis victory.
One note of caution for Mel's troops could be their unexpected losses to Rayo Vallecano and Granada at home in similar situations already this season, but they will be determined to take the chance to finish the year in fourth place, which they will do as long as they better Malaga's result at home to Real Madrid later on Saturday night.
