Uth was treated by medical staff on the pitch for around 15 minutes and attached to a drip after losing consciousness in a clash of heads with Augsburg defender Felix Uduokhai early in the game.
He was eventually carried from the pitch with a neck brace to applause from both teams' dugouts.
Both sets of players -- and Uduokhai in particular -- were visibly shaken by the incident.
Around 45 minutes after Uth was carried off, Schalke announced via Twitter that the striker had regained consciousness.
"Good news: Mark Uth is stable and responsive and is on his way to the hospital with our team doctor," the club tweeted.
