It was confirmed this week that Karl Stefanovic would not be returning to co-host TODAY in 2019.

In a statement about the decision that was shared on Wednesday, Nine's Director of News and Current Affairs, Darren Wick, said, "Nine and Karl Stefanovic have agreed it is time for him to step off the TODAY show. Karl remains on contract with the network and will continue to host This Time Next Year, which records in February."

Wick continued: "For over 14 years Karl has been at the centre of the TODAY show, bringing his unique personality and perspective to the day's news and current affairs. An announcement on the new line up and format of the TODAY show will be made in the coming weeks."

There is growing speculation as to who will replace Stefanovic as the frontman of TODAY, and most of the reports are circling back to one man: Brenton Ragless.

Ragless is currently filling in for Stefanovic anyway (with Deb Knight keeping Georgie Gardner's seat warm over the summer break), so could a full-time transition be on the cards?
