"I thought I was OK," Dickerson said. "I was standing at second trying to focus on smaller things, the back stop. It was tough [but] something I thought was going to go away. I didn't know it would escalate to the degree that it was when I got back out to the outfield."Dickerson, who has suffered multiple concussions over the years, including one when he was in fifth grade, did not require a trip to the hospital. The 27-year-old was examined at Great American Ball Park by a doctor. He will undergo more testing on Tuesday. "I'm doing all right," Dickerson said. "My vision is coming back a little bit. Right now, I feel a little drowsy. I just want to sleep. It's not as hard to focus, which is a good sign. I just had to answer simple questions like, 'What happened yesterday?' It almost took me a while to answer, but I got it." Dickerson's single in the fourth snapped an 0-for-10 streak. In 17 games, he is batting .205 with one home run and five RBIs.
