The goalkeeper was forced off during Saturday’s win over Hartlepool United after being caught by defender Mathieu Baudry early in the game, an incident which left him with blurred vision.
But he is set to return to training on Thursday and is expected to be available for selection on Saturday.
“Marko will train Thursday or Friday but he will be all right,” boss Darren Fergsuon told The Star.

Marosi was replaced during the game by Ross Etheridge, who went on to damage his finger and Rovers are still awaiting the full prognosis.
He said: “Ross has got a fracture of the finger which sounds worse than what it actually is.
“But he’s got something else going on in his wrist.
“He’s went to see a hand specialist on Tuesday and if he says it’s what we think it is, or what’s been x-rayed, then he should be okay for Saturday.
“If it is a little bit more complicated then it might be a couple of weeks for him but I won’t know until later in the week.
“Louis Jones, the young lad, will come onto the bench if Ross is out.”
