Nottingham Forest could be set to play without the services of defender Murillo on Sunday, when Leicester City are the opponents in the Premier League.
The Brazilian centre-back scored the equalising goal as the Tricky Trees drew at Crystal Palace on Monday night, before he was forced off with a leg issue.
It is currently unclear whether Murillo will be fit to feature at the City Ground, where Forest are battling hard to secure a Champions League spot.
If the 22-year-old is unable to step onto the East Midlands turf this weekend, Nikola Milenkovic should be joined by Morato at the heart of the backline.
Earning his maiden league start of the calendar year earlier this week, Ibrahim Sangare impressed in the engine room alongside Elliot Anderson.
That pairing has forced Nicolas Dominguez to play out the left flank, covering for the absence of Callum Hudson-Odoi, who is sidelined with a hamstring strain.
Nuno Espirito Santo possesses more natural options in that position on the bench, though, in the form of Ramon Sosa and Portuguese winger Jota Silva.
Nottingham Forest possible starting lineup: Sels; Aina, Milenkovic, Murillo, Williams; Sangare, Anderson, Dominguez, Gibbs-White, Elanga; Wood
