Manchester City manager Pep Guardiola was unsure of the severity of Rodri's injury sustained in Tuesday's win over Atalanta.
The Spaniard did confirm that it was a hamstring injury that caused his countrymen to be withdrawn in the first-half.
He told BT Sport: "No. Not yet. I think tomorrow we will know and hopefully it will be between 10 days if it is not broken. If it is broken, it will be three weeks or one month."
"Yes, looks like [a hamstring]. I didn't speak with him or the doctor just yet but looks like - when one guy runs and puts their hand in the hamstring position, it is hamstring. It looks like."
