You could have threats to remove the title on Raw if he doesn't defend it and hype all night that Punk's going to have to decide whether to compete injured or give up the title. Heyman will be telling him that you can't go out there and wrestle you have to give up the belt. Punk decides to wrestle and the commentators play up how regardless of what Punk has done they really respect him for having the courage to come out and defend when he can only walk on one leg. Then the Shield comes out from under the ring and attacks whoever he is facing causing a DQ. Then Shield teases attacking Punk only for him to slink out of the ring and stare them down.
Although the 'E won't do this, this is still a good idea.
