Conor McGregor weighed in 3.5 pounds heavier than Floyd Mayweather ahead of their £500million mega-fight.
The Irishman tipped the scales at 153lb, inside the 154lb limit, compared to Mayweather's 149.5lb.
The boxing legend has spent all week insisting that his Irish opponent was struggling with his weight cut.
But McGregor showed no sign of that as he saluted the thousands of fans in attendance.
The UFC star faces a mammoth challenge in his professional boxing debut against the best boxer of his generation.
