Murillo is confident of playing a role in Nottingham Forest's fight for Champions League football despite hobbling off injured after scoring in the 1-1 draw at Crystal Palace.
The Brazilian defender, who has been arguably Forest's best player this term, was forced off at Selhurst Park late in the second half, limping heavily.
Boss Nuno Espirito Santo said the 22-year-old would need a scan to assess the extent of the damage.
While losing Murillo at such a crucial stage of the campaign would be a huge blow for Forest, Mail Sport understands he is making good progress and has not yet been ruled out of Sunday's meeting with Leicester at the City Ground.
