Cubs center fielder Ian Happ left the game at Pittsburgh in the fourth inning Thursday, after fouling a ball back into his own face.

Happ's X-rays came back negative, the team announced, and he walked away with a bruise above his right eye.

"All indications I heard are that it's not too bad," Cubs manager David Ross said. "So, I'll see how he's feeling. Obviously it's a sensitive area."

The foul ball knocked the helmet off Happ’s head and hit him above the right eye. He clutched his face, stepping away from the batter’s box and dropping to his hands and knees. A trainer immediately examined Happ.

Happ underwent a couple on-field tests and dabbed his right eye with a towel before leaving the game. Outfielder Cameron Maybin finished Happ's at-bat and then took his spot in center field.

"It was just super blurry and kept watering," Cubs manager David Ross said. "That's just a dangerous situation."
