Super Eagles coach Gernot Rohr and fans of the national team will be worried after Torino provided an update on the condition of midfielder Joel Obi.

The 26-year-old had to go off 28 minutes after coming off the bench against AC Milan on April 18 after picking up an injury, few days after he was involved in a serious car crash.

Rohr has just over three weeks left before announcing Nigeria's 35-man provisional World Cup roster and the former Inter Milan whizkid was a top candidate to make the squad list, assuming he was in tip-top condition.

Torino have reported via their official website that Joel Obi did not participate in their penultimate workout before the trip to Stadio Atleti Azzurri d'Italia (Bergamo), where the Maroons face Atalanta on game week 34 in the Serie A.

And they added that the instrumental examinations to which the midfielder was submitted showed a small stretch to the left thigh muscle and he'll spend 7-10 days on the sidelines before further checks, which will determine the recovery time for his new injury.

Obi was left out of Nigeria's 2014 World Cup squad list by late Stephen Keshi after the midfielder was unable to prove his fitness during the Super Eagles training camp.
