TeVeS is a relativistic generalization of MOND developed by Milgrom's colleague Bekenstein in 2004. It reduces to general relativity in strong gravitational fields and to MOND in weak gravitational fields, while resolving problems earlier versions of MOND had with phenomena such as gravitational lensing, conservation laws, superluminal modes, and so on.

A paper posted in arxiv this month (http://www.arxiv.org/abs/astro-ph/0504130), by two University of Michigan physicists (Go Blue!), has determined that it is possible to tweak TeVeS to eliminate the need not only for dark matter, but also for dark energy. From the abstract:

Can Relativistic MOND Theory Resolve Both the Dark Matter and Dark Energy Paradigms?

In this paper, we study cosmology within the frame work of a recently proposed relativistic MOND theory and consider the dynamical scalar field of the theory as a possible candidate for dark energy. We also demonstrate, in specific cosmological models, that there is a de Sitter attractor which makes the scalar field play the role of a cosmological constant at late time.
