Tom Felton suffered what appeared to be a medical emergency on Thursday at the Whistling Straits golf course in Wisconsin. The Harry Potter star collapsed while participating in a celebrity golf tournament as part of this week's Ryder Cup. Images show the actor and avid golfer conscious as he was taken on a stretcher from the 18th hole.

Yahoo Entertainment reached out to a representative for Felton but did not immediately receive a response.
