Senger is out of the lineup for Sunday's game against the Athletics.
Senger had started behind the dish in six of the previous seven games, but he'll likely see his playing time take a hit now that Luis Torrens has recovered from a bruised forearm. Senger may soon find himself off the 26-man active roster entirely, as Francisco Alvarez (hand) has already begun a minor-league rehab assignment and is nearing reinstatement from the 10-day injured list.
