Osimhen had opened scoring in the 19th minute, before he was taken off after complaining of chest pain. The Super Eagles striker was replaced by Loic Remy and rushed to a hospital.
After the game, Lille manager Christophe Galtier, allayed fears that Osimhen may face a lengthy spell on the sidelines.
“We just talked to him, he’s fine. Everything is back to normal. He experienced dizziness and pain,” Galtier told Canal+.
