The 25-year-old is nearing the end of his two-month loan deal at the Memorial Stadium after playing 7 games for the Pirates so far. A free transfer is set to go through for Williams to make his stay permanent.
'Rhino' was signed by City in 2001 for a £150,000 fee after impressing in Chesterfield's climb up the league. However, things didn't work out for the Mansfield-born winger in Hull, scoring just twice in 40 league starts and 12 substitute appearances.
