Any link between Plebanski and McDowellMansouri formulations of GR?

Bonjour,
The two can be related to a BF theory, the Plebanski one is the basis of the spinfoam model, the MacDowellMansouri one appears the more "natural" in the context of Cartan geometry. Is the fact that they can both be expressed as a deformed BF theory the only link between them? Merci.
