Real Madrid centre-half Antonio Rudiger is a major injury doubt for the titleholders' Champions League clash with Manchester City.
The German international suffered a right thigh injury and limped off in the first half of Real's 1-0 LaLiga defeat to Espanyol on Saturday.
"Following tests carried out by Real Madrid's medical service Antonio Rudiger has been diagnosed with a muscle tear in his right leg," the club revealed on Sunday.
According to Spanish media reports the player is set to be sidelined for a minimum of two weeks, ruling him out of next week's LaLiga game against Atletico Madrid, and the first leg of Real's Champions League play-off with City on 11 February.
Rudiger's absence if confirmed will be a major blow to Carlo Ancelotti, who is already having to cope with the season-long absences of Dani Carvajal and Eder Militao, both out for the rest of the season.
