England coach Eddie Jones joked that he could name his side for next weekend's match against Argentina a minute before kick-off, after a number of injury concerns prompted a delay to the announcement of the team to face Fiji on Saturday.
Billy Vunipola, Nathan Hughes and Elliot Daly all face further assessment before Jones settles on his line-up for the meeting with Fiji, the second of four end-of-year home Tests for England.
"We've had a really good preparation, albeit with a few injury concerns we're still trying to sort out at the moment," said the Australian on Thursday.
"We'll have those sorted out by tomorrow [Friday], so we'll announce the team tomorrow, which is a deviation from our normal procedure but is in line with the regulations for team announcements."
Asked if England had required special dispensation to name their team after the standard 48-hour deadline, a grinning Jones added: "There's no regulation - we could do [it like] the football, we could name it one minute before the game, which we might next week. Hang on to your hats, that will be a bit of fun."
Jones continued: "Billy and Nathan are still carrying knocks from the previous game, Elliot Daly's still carrying a knock from the previous game, so we're looking to see how they resolve themselves over the next 24 hours before we make a final decision.
"It's just ongoing, sometimes these things take a good turn and sometimes they take a bad turn; you get more information, you get less information, you get good information, you get bad information.
"We're processing all of that and we'll make a final decision tomorrow."
