Julen Lopetegui has been left scratching his head with the need for a solution after it emerged Fernando Reges, a key figure for the Spanish coach, will be absent for the upcoming clash with Atletico Madrid.
The midfielder picked up a yellow card in the clash with Osasuna and is now suspended, yet his misery was compounded when he picked up an injury during a sprint in the first half.
Further tests are set to be done on Monday morning, although it's hoped he will only be on the sidelines for a short period.
Fernando has barely missed a moment of Sevilla's campaign and his loss will be a huge blow.
He has played 28 matches this season and has racked up the fourth highest number of minutes within Lopetegui's squad.
