  We combine the D0 measurement of the width difference between the light and
heavy B_s^0 mass eigenstates and of the CP-violating mixing phase determined
from the time-dependent angular distributions in the B_s -> J/psi phi decays
along with the charge asymmetry in semileptonic decays also measured with the
D0 detector. With the additional constraint from the world average of the
flavor-specific B_s^0 lifetime, we obtain Delta Gamma_s = (\Gamma_L - \Gamma_H)
= 0.13 +- 0.09 ps$^{-1}$ and phi_s = -0.70 ^{+0.47}_{-0.39}. The data sample
corresponds to an integrated luminosity of 1.1 fb^{-1} accumulated with the D0
detector at the Fermilab Tevatron Collider.
