My question is: has any contestant gotten injured DURING a pricing game (such as Time Is Money, Race Game, etc.), and if so, how was it handled on air?
This site's FAQ Timeline has a few incidents mentioned, although technically none during the gameplay portion of a pricing game:
February 16, 1998: "Monday show features Scott, the well-known contestant who injured his knee before a playing of Dice Game; in the wake of his injury, Bob spins the Big Wheel for him."
January 14, 2014: "Judy, the winner of the second Showcase Showdown, hurts her ankle during a wheelie and requires crutches (and eventually a chair) for the rest of the show; to accommodate her, the Showcase is conducted in front of the Turntable. Drew assures the audience that she will be sent to the hospital as soon as the taping ends."
May 20, 2021: "On Thursday, while celebrating winning Grocery Game, contestant David trips over the left side of the Turntable's "doorframe," breaks several of its lights, and ends up stumbling down the stairs behind it; fortunately, he is not badly injured, although his right hand is noticeably bandaged for the rest of the show."
