Jeffers was pinch hit for in the ninth inning of Friday's loss to St. Louis due to a sore hand, Patrick Borzi of MinnPost.com reports. Jeffers went 2-for-3 with a run scored before departing.
Jeffers took balls off his hand twice while behind the plate but was able to continue playing defense. He couldn't grip a bat later in the game, however. It's not clear if Jeffers will undergo testing, but he already wasn't set to catch Saturday. Should he need additional time off, Christian Vazquez would step into a bigger workload.
