Recent Raman scattering data in B{sub 1g} and B{sub 2g} geometries in the superconducting state of underdoped cuprates were interpreted as evidence for two distinct energy gaps. We argue that these data can be equally well explained within a one-gap scenario if final-state interactions are taken into account. In particular, we show that they can account for the differing doping dependences of the Raman peaks in these two geometries and the doping independence of the slope of the B{sub 2g} response.
