We obtain a local regularity result for solutions to K(psi,theta)-obstacle problem of A-harmonic equation divA(x,u(x),del u(x)) = 0, where A : Omega x R x R(n) -> R(n) is a Caratheodory function satisfying some coercivity and growth conditions with the natural exponent 1 < p < n, the obstacle function psi >= 0, and the boundary data theta is an element of W(1,p)(Omega).
