Wilks has scored eight goals and created five in 30 games on loan to Doncaster this season, and McCann had hoped to extend the forward's deal until the end of the season.
But the Rovers manager told the Doncaster Free Press on Sunday that he won't waste his time if an agreement with Wilks - whose future is complicated by the fact that his Leeds contract expires in the summer - is not reached by Wednesday 'at the latest'.
"Until he signs a new contract with Leeds, he won’t be signing his extension here," he said. "We’re hoping that is going to be done on Monday - or the latest, Wednesday.
"He’s not going anywhere else. As soon as he signs that extension he’ll be here. We don’t want any breaks in Mallik’s loan.
"I’ve been very clear with Mallik, his agent and Leeds that if there is a break then I’ll move on."
And having since concluded a deal for Smith, the young Sheffield United forward who scored 10 goals in 23 National League games for Barrow in the first half of the season, could it be that McCann and Doncaster have already run out of patience?
Or could Wilks and Smith yet play together this term?
