In a medium saucepan, mix together the chicken broth, milk, and flour over medium-low heat until it boils - stir constantly. Continue stirring the "chicken soup" until it thickens and then remove from heat.
In a medium bowl, mix together "chicken soup", Greek yogurt, Worcestershire sauce, onion soup mix, and chicken broth until incorporated. Pour sauce over the pork chops.
Cover the crock pot and cook on LOW for 4-6 hours. (I've used thin boneless pork chops and they were done in 3 hours, so check them periodically.)
Remove the pork chops from the crock pot and plate. Pour gravy from the crock pot over the pork chops.
