Although the collision took place within the first three minutes of the game at the Britannia, Huth was remarkably able to play on while wrapped in bandages.
The 28-year-old managed to play the full 90 minutes of Tuesday's 2-2 draw.
Potters boss Tony Pulis said of his centre back's cut: "It's a nasty cut, a warrior's cut.
"He wanted the bandage taken off and stitched up at half-time but the doc said to me, 'Don't let him do that. If he sees it, he might faint!'
"So we stitched it afterwards."
