British duo Callum Johnson and Gavin McDonnell made weight for their world title fights on this weekend's 'Worlds Collide' bill in Chicago.
Johnson challenges Artur Beterbiev for the IBF light-heavyweight title in the early hours of Sunday morning, live on Sky Sports, and appeared in peak condition at 174.8lbs, with the champion matching this weight, comfortably inside the 175lb limit.
The former British and Commonwealth champion has received his first world title shot against the fearsome Beterbiev, who has stopped all 12 of his previous opponents.
McDonnell was in typically trim shape at 121.8lbs ahead of his battle with WBA super-bantamweight champion Daniel Roman, who was a fraction lighter at 121.6lbs for the 122lb fight.
The Doncaster man, twin brother of former world titleholder Jamie, has earned another opportunity at the highest level, having lost on points to Rey Vargas in a fight for the vacant WBC belt.
Heavyweight Jarrell Miller will have a significant size advantage over Tomasz Adamek, with 'Big Baby' tipping the scales at a whopping 317lbs, nearly 100lb more than his Polish opponent, who weighed in at 227lbs.
The New Yorker is within touching distance of a shot at the WBA 'regular' title, and he is also pursuing a fight against unified champion Anthony Joshua.
