Carpi could reportedly send Zinédine Machach back to Napoli, after a fight with two teammates in training.
The French midfielder has been sent on a season-long loan to the Biancorossi, but that could end before the Serie B campaign has even started.
According to the Gazzetta di Modena, the 22-year-old started a fight with two teammates, including a youth player, in training on Tuesday.
No official sanction has yet been handed down, but Carpi are seriously considering terminating his loan.
Machach has previously been in trouble for fighting, having punched Toulouse’s youth team coach Denis Zanko in September 2017.
Yann Bodiger and Driss Khalid had been installed as the first two penalty takers by Zanko, and when Bodiger missed a spot kick during a match Machach became incensed with the coach.
He was released by Toulouse in October of that year, before joining Napoli on a free transfer.
In March he was allegedly involved in a fight with a motorist in Naples.
