Sampdoria have confirmed Gonzalo Maroni did not break his ankle but that the attacking midfielder needs more tests.
Maroni scored on his Samp debut last night, helping his new side beat Crotone 3-1 in the Coppa Italia.
However, the Argentine went off after an hour with a suspected ankle injury.
Tests since then have ruled out the possibility of a fracture, although more examinations are required.
The 20-year-old recently joined the Blucerchiati on loan with an option to buy from Boca Juniors.
