The Athletics placed Medina (knee) on the 15-day injured list Thursday.
Medina suffered a Grade 2 MCL sprain to his right knee in early March during a Cactus League appearance. According to MLB.com, Medina has been able to play catch from his knees recently, and he'll progress to playing catch while standing up once the soreness in his knee subsides. He's still without a clear timetable for making his 2024 debut.
