Victor Osimhen (Nigeria international) will be out of action for at least three weeks after being diagnosed with a grade 2 biceps femoris strain on Friday.

Osimhen left early in Napoli's 4-1 win against Liverpool on Wednesday in a UEFA Champions League game.

“It’s an important region of the muscle,” Doctor Marcello Manzuoli told Tuttomercatoweb."

“In this case, the recovery time hinges on the severity. There are 10/15 days between each degree, which is significant."

“On average, the second tier requires more than a month to resume practicing with the team, not necessarily play in matches."

The former Lille striker will be absent from Napoli's next five matches against Spezia, Glasgow Rangers, AC Milan Milan, Torino, and Ajax.

The striker, aged 23, will also be absent from Nigeria's international friendly against Algeria scheduled for Oran on September 27,

The 23-year old Napoli player joined for EUR80m in September 2020. Since then he has had a terrible injury record, missing what will be 40 matches by the time this latest lay-off is complete.

These injuries were often unavoidable. He dislocated his shoulder while playing for Nigeria against Sierra Leone in November 2020. Then he hit his back during a Serie A match with Atalanta. He was briefly unconscious and was ruled out of three matches.

The worst thing was Milan Skriniar, Inter defender, who clashed heads in November 2021. He suffered multiple facial fractures and required 18 screws and metal plaques to keep it all together.

Osimhen was left on the sidelines almost three months.

This does not include the fact that he was ill at two different times with COVID-19, while on vacation in Nigeria.

This season, the Nigerian has contributed an assist and scored two goals in five Serie A matches.

Osimhen, who signed for the Serie A club in Lille, has been a central figure in Spalletti’s team.

Despite being sidelined on several occasions with injuries, he finished the season with 14 goals in 27 league matches.
