Robinson has missed Blues' last two games after being given a two-game ban for clocking up ten bookings for the season.
"It's huge for us to have our captain back," said Clark.
"Not only is he a leader in terms of his captaincy, but he’s also a leader in terms of his performances.
"Everything about him epitomises what I’m looking for in the group and it's a huge bonus we’ve got him for Saturday."
Clark is also boosted by the availability of Mitch Hancox after injury.
"Mitch trained this morning, so we're getting players back" he said.
"Jon (Spector) is also making progress and will keep training with the group. He had a bit more of an intensive session today."
