Drew remains sidelined with concussion

FORT MYERS, Fla. -- Red Sox shortstop Stephen Drew is still experiencing symptoms from the mild concussion he sustained on Thursday, and was again out of the lineup for Saturday night's game against the Orioles.

"He's improved over yesterday," said Red Sox manager John Farrell. "He went through some bike tests today, where you get him just to exert the heart rate and see if it creates any more of the concussion symptoms. While there were some at the very end, the last sprint that he did on the bike, he is definitely improved over a day ago. What this means going forward, obviously he's day to day. But the improvement is very encouraging."

Drew, who was hit by a pitch from Twins right-hander Caleb Thielbar on the "B" of his batting helmet on Thursday, said this is his first time experiencing a concussion.

"It just squared me up really good," said Drew. "Going through the game, I had no symptoms. I played two or three more innings after that. Went home, was just watching TV, icing my foot and I started getting a headache. That's when the symptoms were coming on, which is probably four hours after.

"I was trying to do some reading and some light blurriness came in the next day. The trainers came in and treated it as a slight concussion. That's where we're at now. We're kind of letting it lay low. I feel a lot better today than I did yesterday. I have more energy and I'm not as tired."

Knowing that there are still more than three weeks before the season starts, Drew will let the trainers be his guide for the next few days.

"I don't know what the next step is. Tomorrow we'll come in, they'll do some more tests, and we'll go from there," Drew said. "I know yesterday I was more out of it than I am today. They're looking at all the symptoms. We've got three weeks before the season starts, so we don't really need to rush into things and get those symptoms back. That's what they're watching out for."
