If a player is immobilized by Graves' GRASPING HANDS and is sent through a Portal with Doorman's LUGGAGE CART the player will be transported through the portal but appear to remain immobilized on the ground, so the cart does not move him, but he will be transported to the other side of the portal.
Also, maybe this can be replicated with Abrams' SHOULDER CHARGE -> Portal
