The Athletics placed Langeliers on the 10-day injured list Sunday due to a torn meniscus in his right knee.
The transaction is hardly a surprise after Jeff Passan of ESPN.com reported earlier Sunday that that the injury could keep the catcher out for the remainder of the season. The Athletics have yet to reveal if Langeliers will undergo surgery, but in the likely event he does, his 2026 campaign would come to an early end. Brian Serven was called up from Triple-A Las Vegas to take Langeliers' place on the 26-man active roster, while Jonah Heim is poised to step in as the Athletics' primary backstop.
