Floyd Mayweather Jnr was released from a Las Vegas jail in the early hours of Friday morning after serving two months of a three-month sentence for domestic battery.
Mayweather declined to comment as he left Clark County Detention centre, meeting a group of friends, including rapper 50 Cent.
Miguel Cotto was Mayweather's last opponent on Saturday, May 5, when 'Money' won an impressive points decision to remain unbeaten.
Mayweather has yet to decide whether he will fight again this year, with a proposed November 10 date for a bout with Manny Pacquiao looking extremely unlikely.
