Would the logical thing not be to move Sportsday to a different time? If the News at One really is a 60 minute bulletin, it would make sense for it to be broadcast on the News Channel (UK feed) in full, thereby displacing Sportsday. Or alternatively roll Sportsday into the News at One, essentially mirroring the sports updates on weekend bulletins.

I wondered if there was piloting or other maintenance to the studio which forced Sportsday out today?

Presumably at some point prior to the News at One there will need to be some pilots done. I seem to recall for similar things in the past the BBC have done pilots that run in parallel to the live broadcast (in a different studio/location). Depending on how soon the move to Salford is this could have been one such pilot.

I'd have thought that once the move to Salford is complete that a sports bulletin might run at half-past whilst the nations and regions opt-out. In which case it would presumably make sense for the sports presenter to be in the same studio. This would then allow the nations and regions to return at :45, with the potential for nations to continue to remain opted out if they wished to have an extended lunchtime bulletin. (This might be politically beneficial to the BBC in the nations.)
