  The modified geodetic brane cosmology (MGBC) is tested with observational
data. The MGBC is derived from the geodetic brane gravity action corrected by
the extrinsic curvature of the braneworld. The density parameter coming from
this additional term produces an accelerated expansion of geometrical origin.
Subject to the Supernovae Ia, Observable Hubble parameter, Baryon Acoustic
Oscillations and Cosmic Microwave Background probes, the obtained fit provides
enough evidence in the sense that the extrinsic curvature effect is able to
reproduce the accelerated expansion of the universe without need of invoking
dark energy, exotic matter or cosmological constant. Moreover the MGBC is free
of the problems present in other braneworld models.
