The Yankees placed Dominguez on the 10-day injured list Friday with a left shoulder AC joint sprain.
Dominguez suffered the injury during Thursday's game against the Rangers when he collided with the outfield wall while making a catch. He managed to avoid a concussion or other major injury, but Dominguez is expected to require longer than a minimum stay on the IL. If Giancarlo Stanton (calf) beats him back from the IL, Dominguez could be sent back to the minors once he's healthy.
