BoSox pitcher Beckett has concussion

Beckett was scheduled to throw in the bullpen Tuesday ahead of a scheduled start on Thursday, but that is now likely to be pushed back. Red Sox manager Terry Francona said the team will have to wait until Beckett is cleared by doctors before he can resume throwing.

The two-time World Series winner said Tuesday he is feeling better after a good night of sleep, though he still has some swelling above his left ear.

"I feel all right. Feeling better today. I feel like I got hit in the head. I'm getting through some of the headache stuff that I had yesterday, which is probably good," Beckett said.

The accident happened before Boston's game against the Twins at City of Palms Park Monday, when Beckett was standing in left-center field shagging fly balls during batting practice.

Coach Ino Guerrero was attempting to hit a ball towards a bucket at second base with a fungo bat when he missed and struck Beckett, who left the field under his own power and was later sent home.

"You go through a bunch of different emotions. First you're pissed because you don't know what happened. Then I tried to walk and I got real dizzy. I kind of took a knee," said Beckett. "You kind of go through everything. I really didn't even know what happened. I didn't know if I got hit by a ball from another field or what. I had no idea what happened."

At first Beckett was annoyed with Guerrero, but said he didn't want to be too hard on him.

"He feels terrible. I didn't want to make things worse," Beckett said. "At first I was pissed. I knew he didn't do it on purpose. It's one of those deals. Was it stupid? Yes, it was very stupid. I think he realizes that now."
