Real Madrid suffered an injury-related selection setback ahead of its Champions League semifinal second leg clash against Bayern Munich according to SPORT, which cited anonymous sources.
Los Blancos are on a high after wrapping up the La Liga title at the Bernabeu on Saturday.
After they beat Cadiz 3-0, bitter rivals FC Barcelona were then trounced 4-2 by Catalan neighbours Girona which made it mathematically impossible to prevent Madrid from clinching a record-extending 36th Spanish top flight crown.
There were positives to take from the victory beyond the milestone, including the return of Thiabaut Courtois.
The Belgian goalkeeper ruptured his ACL training for the start of the season, and finally stepped on the field in a competitive capacity after a knock to his other knee last month delayed his comeback.
Another casualty of the same August period was Eder Militao, who at least made it to the Matchday 1 trip to San Mames against Athletic Bilbao but then pulled up with an identical ACL KO.
Militao became available to Carlo Ancelotti sooner than Militao and played against the Basque side at the Bernabeu last month.
Because of this, the manager expected him to be fit enough for Wednesday's last four meeting with Bayern which will decide who goes to the UCL final at Wembley on June 1.
Yet as reported by SPORT, the Br azilian "automatically" ruled himself out of his team's biggest game of the season with his showing against Cadiz.
Militao was handed a second consecutive start in La Liga, and while physically he appeared fine, the newspaper said that the 26-year-old is still suffering mentally after such a lengthy spell on the sidelines.
He made two serious mistakes as the last man which could have been costly. And while Nacho and Courtois saved him on each occasion, this might be different were the same development to unfold against Bayern who boast world class marksmen such as Harry Kane.
With the score tied 2-2 on aggregate, Ancelotti can't take the risk of throwing Militao into the deep end at the highest level.
In his place, he is likely to select either Nacho or defensive midfielder Aurelien Tchouameni to partner Antonio Rudiger in a back four.
