It would be absolutely horrible if Jr was drafted in to fight in the final because of Groves injury.

Not because I can't stand Jr but because it would mean that the winner had already been beaten and it would devalue the competition, would they consider putting the date of the final back to allow groves to recover or is the date of the final set in stone?

That's if Groves injury is bad enough to rule him out of the current date of the final anyway.
