St Johnstone v Rangers (13:30)
St Johnstone manager Tommy Wright says his side have to be "firing on all cylinders" to get a result against Rangers.
"We have had a lot of games," he tells Sky Sports. "We're going with two up top because we need to win matches to try and get into the top six.
"Games are running out, so we are going to try and be positive, which is going to be difficult against a really good side, but that will be our aim.
"Rangers' second-half performance against Braga was excellent and shows how good they are. They won't want to lose ground on Celtic.
"We gifted them goals in the second-half last time - we can't do that. We need to be firing on all cylinders and we have people who can cause them problems"
