Any link between Plebanski and McDowell-Mansouri formulations of GR?

Bonjour,
The two can be related to a BF theory, the Plebanski one is the basis of the spin-foam model, the MacDowell-Mansouri 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.
