Yankees second baseman Robinson Cano left Sunday night's game in the sixth inning after being hit with a fastball from Orioles left-hander Troy Patton.
Manager Joe Girardi said X-rays were negative.
"He's fine," Girardi said after the Yankees' 6-3 loss. "There are no broken bones. It's just a contusion. He's sore."
The team will re-evaluate Cano on Monday.
On the play, Cano swung through the pitch and was hit in the left hand. He immediately grabbed his hand.
Yankees trainer Steve Donohue rushed out to attend to Cano, who walked off the field and into the clubhouse.
