Has anyone ever seen a disabled person as a contestant on The Price Is Right?

I have watched this show off and on pretty much my entire adult life. On Wheel of Fortune there have been contestants in wheelchairs, who needed someone to assist with spinning the wheel. On Jeopardy they have had blind contestants who were given braille sheets with the categories on them. There may have been those in wheelchairs on Jeopardy too, but I am not sure. But on The Price Is Right, I have never seen anyone with any kind of handicap picked as a contestant. I have never seen anyone in a wheelchair as a contestant. I may have seen a crutch or two but not because it was anything more than a broken foot or something that would heal over time, and the contestant was able to climb the steps to get up on stage. Does this mean that this show discriminates against the disabled? Do they have a ramp available should a contestant in a wheelchair actually be chosen and win a spot up on stage? What about games like Plinko where the contestant has to climb steps to play? Would they allow someone to assist the player in the wheelchair? What about a blind contestant? Would there be a way for them to use braille to help a blind contestant play the game? Is it a fair game if it does not allow disabled people to play? Would you like to play the game if you had the chance but had to use a wheelchair?
