Fermin is out of the lineup for Sunday's game against the Angels.
After taking a foul tip off his catcher's mask and being forced out of Wednesday's 7-6 win over the Mariners, Fermin didn't appear in the Padres' subsequent two games. He returned to the lineup Saturday and caught all nine innings of the Padres' 4-1 win, going 1-for-2 with two walks and two runs. Fermin didn't experience any reported setbacks coming out of that contest, so he's presumably just getting some rest for a day game after a night game.
