The mailmen are aiming at bouncing back from a shock 1-0 defeat to Sofapaka by bagging maximum points against the Millers.
Head coach Sammy ‘Pamzo’ Omollo is confident of a good result, but has cautioned his charges against underrating their opponents.
"There are several players who are out injured; Dennis Mukaisi, Suleiman Ngotho and Sammy Okinda will be missed; they are good players who will definitely be missed but we have replacements who are ready for the task.
"It is a tight encounter, we lost and they lost as well meaning it will be a tough match since we need points and they do as well."
Rangers are twelfth on thirty-four points.
