The Malaysian has granted the Scot a reprieve after last week demanding that Mackay resign or be sacked, with the pair agreeing to holding talks to resolve their issues.
Mackay had asked that those took place before the Welsh side faced Southampton on Boxing Day, only for that request to be denied. His future will likely depend on a reconciliation with Tan and the Cardiff manager acknowledged yesterday that he did not expect to still be in the job after the weekend.
"I did feel I was going to lose my job on the weekend. I expected to be sacked," said Mackay. "I wanted [to meet Tan yesterday] but that was declined. If not, then [today] but that was also declined."
