Searches for a light sterile neutrino have been performed independently by the MINOS and the Daya Bay experiments using the muon (anti)neutrino and electron antineutrino disappearance channels, respectively. In this Letter, results from both experiments are combined with those from the Bugey-3 reactor neutrino experiment to constrain oscillations into light sterile neutrinos. The three experiments are sensitive to complementary regions of parameter space, enabling the combined analysis to probe regions allowed by the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE experiments in a minimally extended four-neutrino flavor framework. Stringent limits on sin^2 2?µe are set over 6 orders of magnitude in the sterile mass-squared splitting ?m^2 41. The sterile-neutrino mixing phase space allowed by the LSND and MiniBooNE experiments is excluded for ?m^2 41 < 0.8 eV^2 at 95% CLs.
