DETROIT -- Texas Rangers outfielder Daniel Robertson passed a concussion test after Alex Rios' knee hit Robertson's face as the two tried to catch a ball in shallow right-center field hit by Ian Kinsler in the third inning Thursday against the Tigers.

Robertson has some bruising and swelling and went to the hospital to undergo some tests. A CT scan showed a couple of nondisplaced facial bone fractures and he'll see an ENT in Detroit. General manager Jon Daniels said the club will make a roster move on Friday. The club confirmed that the object that flew out of Robertson's mouth when he was hit was gum, not teeth.

Robertson, who was back in the clubhouse after the game, said it was just a "hustle" play and that he and Rios couldn't hear with all the noise.

"It was just bad luck," Robertson said. "I heard my gum went pretty far."

Robertson had a single, was caught stealing and grounded out before leaving. He is 3-for-20 this season and was batting leadoff Thursday against left-handed starter Robbie Ray. Shin-Soo Choo moved to the 3-hole with Prince Fielder out with a herniated disk in his neck.
