According to reports, the 22-year-old crashed to the ground after 24 minutes in the encounter eventually won 1-0 by Gent, sparking fears that he had broken his leg.
The former Ajax player, who helped the Super Eagles qualify for the Russia 2018 World Cup, was rushed to hospital for urgent attention.
Grave concerns were held for the possibility of the former Slovakia-based winger, who has scored five goals for the Buffalos this term, representing Nigeria at the summer World Cup.
However, Brussels-based newspaper Het Laatste Nieuws reported late on Tuesday that Simon only suffered a serious leg wound.
“Good news about the situation of Moses Simon, who was injured during the practice match against Nuremberg. Photos showed a severe bruise, but no break,” the newspaper wrote.
The player, who withdrew from Nigeria’s friendly against South American powerhouse Argentina in Krasnodar, Russia, on November 14 due to injury, has been linked with a £6m move from Gent to relegation-threatened Premier League club West Brom in the January transfer window.
He has also been linked with the likes of West Ham, Swansea and Stoke.
