Ideas on how to occupy an injured pup?

My husband took a tumble onto our 6-month-old pup, Scarlett, and broke her foot on the outside metatarsal. We have to keep her immobilized for 8 weeks. We have a 1 1/2 year old shepherd mix and all they want to do is play. Any suggestions to keep her occupied and still? She has pain meds and sedatives and a crate but she just wants to run and jump with her older brother.
