The Brighton man, who was said to be the smaller man during the build-up after fighting most of his career at middleweight, weight almost one pound heavier than Groves (167.1lbs) for their forthcoming bout.
Both men looked in great shape as they prepare to battle it out for a place in the lucrative final of the eight-man tournament on Saturday night at Manchester Arena.
Groves has drifted in the odds since the contest was first sealed by respective quarter-final knockouts as Eubank is hotly favoured to unify the WBA and IBO belts.
