Dickerson sported a welt near his left eye and a small gash on his forehead as he returned to the Yankees, having been drilled in the batting helmet by a Mike Gonzalez fastball in the 15th inning of Wednesday's 4-1 New York win over Baltimore.
"It could have been so much worse," Dickerson said. "Every time I look at the replay, if you don't look down just in time, it hits you right in the face -- right square in the eye. I just feel extremely fortunate today."
Doctors said that a CT scan showed a slight concussion, although the Yankees did not have immediate plans to place Dickerson on Major League Baseball's new seven-day disabled list for concussions.
Yankees manager Joe Girardi said that he would stay away from using Dickerson on Thursday but expected him to be available for Friday's Subway Series opener against the Mets.
"He is doing OK," Girardi said. "The results came back good, and he's just going to be day to day. He said he felt pretty good last night. I talked to him today. He said he had a headache, but he felt OK."
Dickerson spoke with Gonzalez on the field before Thursday's game, accepting the hurler's apology. Though Gonzalez was immediately ejected, Dickerson said he did not believe he was being thrown at by the lefty, who had just given up a go-ahead two-run double to Robinson Cano.
"Absolutely not," Dickerson said. "He threw two great pitches to start off the at-bat, two great curveballs. If you're going to retaliate for something like that, you're going to do it first pitch."
Dickerson said that after coming out of Wednesday's game, he saw a replay in the Yankees' clubhouse and even asked medical personnel to wait a few moments so he could review it for himself.
"You hear the sound, and I think it's when it really hits you," Dickerson said. "It's scary, hearing that helmet snap and looking over at the broken helmet."
