Must we permit transitional work following off-duty injuries?

Q. An employee was injured away from work. He is now demanding to return to work as an accommodation for his injuries, which he claims is a disability under both the ADA and Minnesota Human Rights Act. We do have a transitional work program, whereby we create work to aid workers injured on the job in returning to work. The work involves duties that we otherwise outsource, such as floor sweeping, etc. Our injured employee is not able to return to his prior position due to the physical nature of that job, and is now demanding that we provide him this sort of transitional work. Must we?
