The cricket.com.au commentators were worried about the blow, initially thinking it hit White in the helmet or throat.
"It just slipped out of his hand, Billy Stanlake, and Cameron White has copped it," the commentator said. "It was certainly dangerous."
Doctors cleared White but the ball seemed to rattle the 35-year-old, who wasn't able to kick on.
White struggled after the blow, limping to 10 off 35 balls before being caught by Chris Lynn after top edging a pull shot off Jack Wildermuth.
Stanlake improved from there to have 1-29 off six overs.
