Marshall, 28, was dropped by Potter for the trip to Sydney and bottom-of-the-table Tigers eventually lost 54-10.
But Potter has reinstated the influential stand-off ahead of this week’s visit of North Queensland and Marshall has defended his coach’s decision.
He said: “There’s only one way to get out of a slump and that’s to play yourself out of it. You play well, everyone shuts up.”
Tigers host North Queensland on Friday night at the Leichhardt Oval.
