The crew built York a slanted wall for him to lean on in between scenes, which, during the first two seasons, allowed York to manage his back injury with little difficulty. Halfway through the third season, York's back injury was aggravated into a painful degenerative spine condition, frequently causing shooting delays while York required assistance to walk around. Sometimes, York would seize up in debilitating pain, so the scripts for some of his later episodes on "Bewitched" were written around his being in bed or on the couch for the entire episode. York did not appear in a handful of seasons-three and four episodes, and by halfway through season five, was barely appearing at all, causing the series to focus more on Samantha and other members of her family, with mentions that Darrin was away on business.
