Red Sox manager John Farrell confirmed that Dustin Pedroia has some symptoms that are consistent with a concussion.

Pedroia left the game in the second inning after being hit in the head with another players' arm. Head injuries are tricky, so it's tough to tell how long he'll be out for (if he even has a concussion), but he was taken out of the game immediately and appeared to be in pain. He'll go through the league's concussion protocol, but if he has a concussion, the Red Sox will likely play it safe with him and give him plenty of time as they're out of contention.
