After Carl Frampton suffered defeat in his rematch with Leo Santa Cruz, we pick out a number of talking points from an eventful weekend in Las Vegas.
But another exciting battle between Frampton and Santa Cruz was not the only abiding memory as Floyd Mayweather and Mikey Garcia attempted to steal the limelight in Sin City.
After their reckless shootout in New York, Frampton and Santa Cruz tried to display more discipline in the second fight, but could not resist the temptation to stand and trade on occasions during another entertaining encounter.
Santa Cruz showed his underrated boxing skills from the start as he forced Frampton on the back foot with an accurate jab and spearing right hands.
'The Jackal' displayed his teeth in the middle rounds, threatening to smother Santa Cruz with relentless aggression, but the home favourite finished strongly to edge 115-113 ahead on two of the scorecards, while the third judge scored it a 114-114 draw.
Both men expressed their desire to meet again in post-fight interviews, but Frampton might have to head back to America for the third fight instead of a planned homecoming bout in Belfast.
Before Frampton and Santa Cruz had even reached the ring, Mayweather attempted to outshine them by announcing he was likely to battle UFC star Conor McGregor in his 50th fight.
The 39-year-old is set to make his return as the biggest name in boxing after telling Sky Sports that he will "most likely" share the ring with the hugely popular McGregor.
Arguments will rage between fans of boxing and MMA about who will emerge the winner, but the pulling power of both men cannot be denied as they would pocket massive pay days.
Santa Cruz ended the night with a sweet revenge victory, but Garcia, another Californian, had arguably produced an even more impressive victory when he ripped the WBC lightweight belt from Dejan Zlaticanin with an explosive knockout.
A contract dispute sidelined Garcia for over two years, but he gave fight fans a reminder of his classy ring skills as he dissected Zlaticanin's defences with ease before delivering a fight-ending right hook.
Garcia, a three-weight world champion, is still only 29 and will target further impressive victories, starting perhaps with the winner of the Jorge Linares-Anthony Crolla rematch in Manchester on March 25.
After a frustrating spell of inactivity, the Welshman had hoped to showcase himself in the sport's capital, but once again is facing an uncertain future.
Talk of a big domestic clash with Frampton will be forgotten for now, with the Northern Irishman pushing for a third fight against Santa Cruz, and Selby desperately needs a fight, and soon.
Josh Taylor has been highlighted as one of Britain's rising talents after winning the Commonwealth title in just his seventh fight, but the 26-year-old was not happy with himself after being taken the distance for the first time by tough Mexican Alfonso Olvera.
The Scotsman was too hasty in his attempts to impress the American audience, receiving a point deduction for a low blow, although he did give a glimpse of his power when a left hook wobbled Olvera in the fourth round.
Taylor will probably continue the learning process in the domestic division for a little longer, but a number of exciting super-lightweight battles could lie ahead, including a grudge fight with Londoner Ohara Davies.
