Silvester, a once touted Filipino hopeful, was once 19-3-1 (15) and regarded as a genuine contender. In fact in July 2012 he took on the then WBC Super Flyweight champion Yota Sato and was ranked #1 by the WBC leading into that bout. Since that bout however he has struggled to create much in terms of career momentum, in fact after losing to Sato Silvester has gone 8-7-1.
Although struggling for form Silvester has been mixing with excellent quality of opponents, facing the likes of Adrian Young, Thabo Sonjica, Rey Vargas and XiaoJun Qiu and the men beating him would be favoured over Jackson at this point.
As for the Australian Jackson competed at the 2012 Olympics, losing to Liu Qiang in his opening contest. and turned professional the following year. His career took some time to get going but in 2015 he claimed the Australian Featherweight title, defeating Will Young. He built on that win, and earlier this year he claimed the WBA Oceania Featherweight title, with a win over John Mark Apolinario, a former world title challenger.
With an unbeaten record Jackson is showing promise but this is a big step up in class for the 31 year old who now knows it's time to push forward with his career. A win over Silvester will be the first step for Jackson to get big bouts, but it's a tough first step, even if Silvester has been struggling the past few years.
