Contreras left Thursday night's contest against the Rangers in the eighth inning after being hit in the hand by a pitch, Mac Cerullo of the Boston Herald reports.
Contreras took a 92.3-mph sinker off his right hand from Texas reliever Jakob Junis with a runner on and no one out in the top of the eighth frame. Contreras was in obvious discomfort, and he was immediately replaced for pinch-runner by Isiah Kiner-Falefa. More information on the status of Contreras will likely be provided following the conclusion of Thursday night's game.
