In the Bogomol'nyi-Prasad-Sommerfield (BPS) limit of\nEinstein-Yang-Mills-Higgs theory, we construct numerically a non-Abelian\nwormhole supported by a phantom field. The probe limit is the Yang-Mills-Higgs\nfield in the background of Ellis wormhole when the gravity is switched off. The\nwormhole solutions possess the Yang-Mills-Higgs hair in the presence of\ngravity; Thus a branch of hairy wormhole solutions emerge from the Ellis\nwormhole when the gravitational coupling constant increases. We find that the\nmass of wormholes and scalar charge of phantom field increase monotonically\nwhen the gravitational coupling constant increases. The wormhole spacetime\npossesses double throat configuration when the gravitational strength exceeds a\ncritical value. Surprisingly, the wormholes satisfy the null energy condition\nin the large gravitational strength. We also briefly discuss the redshift\nfactor.\n
