Unified World 154lb Champion Julian 'J-Rock' Williams (27-1-1, 16 KOs) defends his WBA and IBF belts in a Philadelphia homecoming against the hard-hitting Jeison Rosario (19-1-1, 13 KOs) on Saturday 18th January, live on BoxNation.
In the chief support bout, 13-0 (5 KOs) rising star Chris Colbert meets former World Champion Jezreel Corrales (23-3, 9 KOs) for the interim WBA Super-Featherweight belt.
Williams captured his two World Titles in a thrilling upset victory over Jarrett Hurd in May, executing a brilliant gameplan against the physicality and strength of 'Swift'. Hurd also fights live on BoxNation on January 25th, hoping to set up a rematch with Williams this year.
This homecoming will be Williams' first outing in Philly since 2011. He bounced back from a 2016 loss to Jermall Charlo with four straight victories before Hurd, including wins against Ishe Smith and Nathaniel Gallimore.
Dominican-born Rosario, 24, fights out of Miami and faces a tough test against the new World Champion.
He holds solid wins over Justin DeLoach and Jamontay Clark, but only edged past Jorge Cota on a split decision in his last bout and was also stopped by Gallimore in 2017.
Williams could be set for a huge 2020 if successful again in a rematch with Hurd, or a revenge mission against WBC Champion Charlo.
