Rodri was forced off during Manchester City's Champions League match against Atalanta, with the Spain international suffering an apparent hamstring injury.
Shortly after Sergio Aguero had scored his second goal of the night from the penalty spot to put City 2-1 ahead, Rodri - playing again in the unfamiliar position of centre-back - missed a defensive header to let Atalanta forward Alejandro Gomez through on goal at the Etihad Stadium.
The former Atletico Madrid man recovered his ground to make a well-judged tackle but instantly raised his hand to gesture for treatment.
