I doubt it too, but a hip replacement is not a surgery where they don't want you to put any weight on it for 8 weeks. In fact, they want you to start walking as quickly as possible. I'm not sure how Payton could be on the sideline without putting any weight on the knee.
According to this, there are forms of hip replacement surgery where you can put weight on the leg immediately:
"If you have undergone cemented or hybrid hip replacement, you can put some weight on the leg immediately using a can or walker, and you should continue to use some support for 4 to 6 weeks to help the muscles recover."
