BBC Breakfast viewers would have spotted an unexpected change in the line-up as familiar face Jon Kay was noticeably missing from his regular slot alongside .
Jon usually presents with Sally between Monday and Wednesday but during Wednesday's (March 26) episode of the hit show, he was not seen, leaving co-host Sally to team up with stand-in presenter Roger Johnson.
In addition to Sally and Roger, the programme featured John Watson delivering the day's sports news and Simon King providing weather forecasts.
Currently, Jon hasn't commented on his absence via his social media and both presenters on the programme didn't offer viewers an explanation.
It comes as Sally Nugent playfully issued a warning to BBC Breakfast weather presenter Matt Taylor during Tuesday's (March 25) edition of the show.
During one segment, Sally and co-star Jon discussed the white spiral many people had spotted in the sky on Monday evening (24 March).
BBC viewers had sent in photographs of the unique view, which is believed to have been caused by the latest SpaceX rocket launch.
The duo then welcomed weather presenter Matt Taylor to the discussion about the sky, and Sally issued Matt a cheeky warning after he made a fun quip.
Jon went on to say: "Matt's with us this morning! I guess the fact that it was clear skies in a lot of places really helped with the visibility".
Matt responded: "It was beautiful, wasn't it? It's almost like a portal to another dimension, isn't it?"
Sally warned her co-star: "Don't say that, Matt!" with the trio all bursting out into laughter, as Matt attempted to compose himself ahead of his next weather segment.
He then explained: "But yeah, that spiral is caused by the rocket fuel. The rocket was actually rotating at the time, it ejected it. So that's why you get the spiral."
The white cloud-like shape was visible for several minutes in parts of England and Wales, as well as locations in Europe. It is believed to have been caused by leftover fuel from a rocket.
