Beckham was covering second base on Juan Rivera's double in the third inning when the throw from center fielder Alex Rios bounced over his outstretched glove and hit him in the left eye. Beckham fell to the ground and the trainer and manager Ozzie Guillen ran to his side.
Beckham was able to walk off the field, but held his cap over the side of his face. Exposing his face ever so briefly, cameras caught a a bruise and severe swelling along his left cheekbone.
"He looked like he fight (Manny) Pacquiao," Guillen told reporters after the game. "The last time I saw him it looked like (Antonio) Margarito fighting Pacquiao. He had bruises all over the place. I don't think it's broke. I don't know anything about that, but he got lucky. I'm not going to say he got hit in the right spot but it could have been worse."
The White Sox said Beckham is undergoing X-rays. A team spokesman who texted ESPNChicago.com's Doug Padilla said the White Sox are "checking for fractures in (the) lower orbital area" and Beckham's "left eye is functioning like normal."
Guillen doesn't think the Sox will have to make a roster move to replace Beckham.
"We're going to see. I think he should be fine. I hope there is nothing broke. If something is broke then we have to do something about it."
