Real Betis midfielder Nosa Igiebor is a major injury worry ahead of the clash against Rayo Vallecano on Sunday, April 20.

During training on Wednesday, the 23 - year - old suffered discomfort on his left knee and could not complete the exercise.

The Nigeria international tried all he could to resume training but this was not successful, despite receiving treatment from club medic Dr. Tomas Calero.

Nosa Igiebor  managed to return to the pitch after that treatment but the problem persisted and he had to leave the pitch.

He has made 11 appearances ( 1 goal ) for the Andalusian outfit this term.
