LAS VEGAS – Manny Pacquiao and Adrien Broner spent most of this week cracking jokes and smiling while promoting their fight.

Both boxers stood, stone-faced, as they stared at one another Friday afternoon at a weigh-in that drew a few thousand fans to MGM Grand Garden Arena. Pacquiao eventually cracked a smile before they parted ways.

Moments earlier, the 40-year-old Pacquiao stepped on the Nevada State Athletic Commission’s scale at 146 pounds for their Showtime Pay-Per-View main event Saturday night at MGM Grand Garden Arena. Broner, 29, weighed in at 146½ pounds, half a pound below the welterweight limit of 147.

The Philippines’ Pacquiao (60-7-2, 39 KOs) is listed as approximately a 3-1 favorite over Cincinnati’s Broner (33-3-1, 24 KOs, 1 NC) at MGM Grand’s sports book. They’ll fight for the WBA world welterweight title Pacquiao won by knocking out Argentina’s Lucas Matthysse (39-5, 36 KOs, 1 NC) in the seventh round of his last fight, July 15 in Kuala Lumpur, Malaysia.
