FORT MYERS, Fla. -- Red Sox shortstop Stephen Drew didn't play Friday night due to what the club believes is a mild concussion, sustained when he was hit by a pitch on Thursday against the Twins.
"Throughout the night, there were some symptoms of a mild concussion that came on after being hit by the pitch yesterday," said manager John Farrell. "That's why he was in the lineup initially and then when he came in, [we] determined that we've got to give it a day or two to clear up."
At first, Drew seemed unfazed by the pitch that hit his batting helmet.
"At the time, he was like, 'Imagine if this hit me in the nose.' Fortunately it glanced off the helmet, and in the way he reacted, you'd almost think he didn't see the pitch completely," Farrell said. "There wasn't a whole lot of diving out of the way. It wasn't a direct blow. At the time, he felt fine throughout the game. But it was last night when he started to read a book, the print started to get a little fuzzy on him and that's where -- obviously it was precautionary, and, by rule, he's being held out."
Teams are required to follow specific MLB guidelines while dealing with concussions.
"Dr. [Gary] Green in New York, who is responsive, whether it's weekends or not, that's the doctor we'll go through," Farrell said. "It's checking those symptoms in the training room, and then if need be, there's an on-line test he'll have to go through if we get to that point."
