Floyd Mayweather and Manny Pacquiao have squared up to each other for the last time before their multi-million dollar contest in Las Vegas.
In front of a packed crowd at the MGM grand Garden Arena the two boxers weighed in ahead of Saturday's highly anticipated welterweight showdown.
Pacquiao tipped the scales at 145 pounds while Mayweather registered 146 pounds for what is being billed as the 'Fight of the Century'.
Dressed in a bright red track suit, Pacquiao waved and raised his fists into the air as he slowly made his way to the stage in contrast to Mayweather who was serious and focused, rarely looking up from under the brim of his 'Money Team' baseball cap.
After the weigh-in, the two welterweights moved to the front of the stage for the traditional stare down, the smaller Pacquiao looking up at Mayweather with a challenging smile while the stone-faced American stared straight-ahead unmoved.
"I have been fighting bigger guys like [Antonio] Margarito and [Oscar] De La Hoya," said the Filipino.
"It doesn't matter to me. I feel tomorrow that the Lord is always with me and gives me strength."
The showdown between the two best boxers of their generation has been more than five years in the making and at more than $400 million is expected to be the biggest-grossing prize fight of all time,
Barry McGuigan believes that Floyd Mayweather has the edge on Manny Pacquiao in their superfight this weekend.
"I think Mayweather has the edge just simply because psychologically he is unbeaten and by his very nature he doesn't know how it is to lose," said McGuigan, speaking at the BT Sport Industry Awards.
"He has the edge in speed...and he's a bigger man so I give him the edge but Pacquiao has the ability and all of the qualities to beat someone like Mayweather."
The most lucrative fight in boxing history will see the two fighters share a purse of around £198m, with Mayweather rumoured to be taking home a 60/40 majority.

Mike Tyson has labelled Floyd Mayweather "delisional" for comparing himself with Mohammed Ali, and admits accused the boxer of being too scared to take his children to school.
Former heavyweight world champion Tyson made a surprise appearance at the final press conference before this weekend's super-fight, and told UCN:
He’s very delusional. He can't listen. If he was anything like Ali he would take his kids to school by himself.
Greatness is not guarding yourself from the people. Greatness is being accepted by the people. He can't take his kids to school by himself. He’s a very small, scared man.

Roy Jones Jr, a former four-weight world champion, believes Pacquiao's speed and work rate will trouble Mayweatherwhen the welterweight rivals meet at the MGM Grand in the early hours of Sunday morning.
"Manny's best game plan is pressure, pressure. Floyd has never fought an opponent like Manny who throws so many punches, has power in both hands and is southpaw," Jones told Press Association Sport.
"If you look back to Zab Judah, he is the closest to that and he gave Floyd a good run in the first four rounds. After that he started to decline.
"Everyone knows that's Zab's MO, he declines after four rounds. But Manny doesn't decline after four rounds, he goes higher.
Mike Tyson has been forced to deny he's hosting a lavish party at his old Las Vegas mansion this weekend.
Rumours had circulated about Tyson throwing a bash to celebrate Saturday's mega fight between Floyd Mayweather and Manny Pacquiao.
I am NOT hosting a party fight night at "Mike Tyson Mansion". If you got a flyer & was misled into thinking I would be there it's not true.
People call the Vegas house I use to live in Tyson Mansion & it's misleading. I moved yrs ago & never plan on stepping foot in there again.
But the former heavyweight champion took to Twitter this morning and explained he has no intention "on stepping foot" in his old property again.
Pound-for-pound greats Mayweather and Pacquiao finally meet at the MGM Casino, Las Vegas, on Saturday night following years of failed negotiations.
Bob Arum believes Floyd Mayweather's declaration that he will soon retire after sensing the unbeaten American has fallen out of love with boxing.
Arum's Top Rank are joint promoters of Mayweather's showdown with Manny Pacquiao in Las Vegas on Sunday in what will be the penultimate assignment of the 38-year-old's six-fight deal with Showtime.
Toppling Pacquiao at the MGM Grand would register a 48th victory and leave him just one short of equalling Rocky Marciano's hallowed 49-fight unbeaten mark.
Mayweather's insistence that he has no desire to eclipse Marciano has been met with widespread scepticism but Arum, who promoted the reigning pound-for-pound king for the first decade of his career, predicts he will soon hang up his gloves.
I believe what Floyd is saying in that he is looking towards retirement. He's been at it since he's eight years old and he doesn't enjoy it like he used to.
Like Marvin Hagler said, millionaires sleep in silk pyjamas and don't like to get up in the morning and do roadwork.
When he retires, I think Floyd will be a great party guy. He'll have plenty of money and he'll enjoy himself. I just hope that for his sake he settles down and lives a more normal family-type life.
Freddie Roach believes Floyd Mayweather has been forced into a fight he would rather avoid and questions whether the American will even turn up for his welterweight epic against Manny Pacquiao.
Mayweather and Pacquiao collide in Las Vegas in the early hours of Sunday morning with the outcome of the showdown at the MGM Grand deciding who is the greatest boxer of their generation.
Roach believes the 38-year-old's television paymasters Showtime, who have outlaid a minimum of £130million for a six-fight contract, ordered the clash the boxing world has craved for the last five years.
I don't know why Floyd's been so quiet. I'm wondering if he's going to show up, I really am.
At the first press conference I said we were going to kick his ass, but there was no response. His speech was very low-key and subdued. I'm not sure he is going to show up.
I think Floyd was forced into this fight and it's not a fight he wants. He always gets to pick and choose his opponents, but he wasn't able to pick and choose this one because Showtime wanted this fight.
