Crotone forward Emmanuel Riviere has been diagnosed with a Grade I thigh strain.
The 30-year-old scored in his season debut, a 4-1 defeat to Genoa on September 20.
He had a calf injury, made his comeback in stoppages in the 4-2 loss to Cagliari, but then sustained another problem in training. A statement from Crotone confirms Riviere has been diagnosed with a Grade I thigh strain in his right leg.
This sort of injury tends to require one to two weeks on the touchline.
