Kylian Mbappe’s status for next week’s Spanish Supercopa is in serious doubt after the Real Madrid star suffered a sprained left knee in training.

The France international star will miss Madrid’s first match of 2026 at home on Sunday against Betis, and French publication L’Equipe reported that Mbappe is expected to be sidelined for at least three weeks.

“Following tests carried out today by Real Madrid Medical Services on our player Kylian Mbappe, he has been diagnosed with a sprain in his left knee,” the team said in a statement Wednesday. “His progress will be monitored.”

Madrid will travel to Jeddah, Saudi Arabia, for the Supercopa, with a semifinal match against Atletico Madrid on Jan. 8 ahead of a potential final against Barcelona or Athletic Club on Jan. 11. Marca also reported that Mbappe may not travel with the team to Saudi Arabia.

Whether he will be able to return for a Copa del Rey Round of 16 match the following week is also in doubt.

Mbappe, who leads LaLiga with 18 goals, has started all 18 of Madrid’s games so far this season. He missed their Champions League game against Manchester City on Dec. 19, but returned to play 90 minutes over three games leading up to Christmas.

Earlier this month, Mbappe tied Cristiano Ronaldo’s club record with his 59th goal in the calendar year.
