During Rayo Vallecano's 1-1 draw with Sevilla over the weekend, the adventurous center-back suffered an injury that forced him to leave the game in the 35th minute.
The 26-year-old will miss the rest of the campaign, according to sources in the Spanish media.
Mumin has played in 24 of Vallecano's 26 La Liga games this season, making him a vital member of the team. He leads the league in blocks as well.
Prior to Ghana's 2026 FIFA World Cup qualifying matches against Chad and Madagascar on March 21 and 24, respectively, his injury represents a significant setback.
The defender may make a comeback for matchdays seven and eight of the qualifiers, but it is now anticipated that he will miss two important games.
Mumin is wearing two Black Stars caps.
