Fermin (head) is not in the lineup for Thursday's game versus the Mariners.
Fermin had to depart Wednesday's contest after taking a foul tip to the mask. Per Jeff Sanders of The San Diego Union-Tribune, Fermin does not have concussion symptoms and expects to be available off the bench Thursday, though the Padres' team doctor will have the final say. Luis Campusano is catching and batting eighth for San Diego in Thursday's series finale.
