Nothing like a good magical curse or disease!
Give the leaving character a disease that can't be solved by magic alone. The party can go on a side quest to find a cure for magical leaping crotch pheasants or the party moves on.
You can also have the player make a bunch of rolls and record the rolls. Then play the character and use the roll results in the order made. This is like some of the other options already given, the player has to buy in.
