O'Hoppe (head) exited Sunday's contest against the Athletics in the seventh inning, Jeff Fletcher of The Orange County Register reports.
O'Hoppe was struck in the head/neck area by the backswing of Jacob Wilson in the top of the seventh inning, and he ultimately left the contest as a result. The catcher was replaced behind the plate by Travis d'Arnaud, and O'Hoppe's status will likely be updated in the near future.
