However, before their Premiership showdown at Bath on Friday night, McCall confirmed the new deals were not yet set in stone.
“Maro and Jamie have agreed something in principle, but I’m not sure there’s a contract on the table as it stands,” he added.
“It’s pretty important it gets sorted as quickly as possible.”
McCall says the limbo has not yet affected Saracens’ plans for next season, but any further delay could disrupt recruitment.
“Hopefully not – but we will have to wait and see,” he said. “It has the potential to change things I suppose.”
Meanwhile, McCall fears centre Olly Hartley, who has enjoyed a breakout season, could be out for a significant period with a knee injury suffered against Gloucester at the weekend.
However, there is positive news concerning England centre Alex Lozowski, who is nearing a return after a long-term injury absence.
