Billy officially joined Sunderland on a free transfer in July 2014 after three years with West Brom.
The former England youth international is vastly experienced, having made his senior debut at Crewe as a 16-year-old.
Jones' first room-mate with the Railwaymen was none other than David Vaughan, who had a spell on Wearside after joining from Blackpool in summer 2011.
Having broken through from Crewe’s Academy in 2003, Jones went on to win the club's Young Player and Goal of the Season awards in his first campaign.
A Player of the Year award followed in 2005-06 before Jones joined Preston in June 2007 having made 143 appearances for Crewe.
He featured in 174 games in four seasons at Deepdale, playing a key role for North End, winning another Player of the Year award in 2010-11 prior to joining West Brom in summer 2011.
Jones made his Barclays Premier League debut in a 2-0 Albion home win over Wolves in October 2011 and made 74 appearances in three seasons in the Midlands.
The defender made his Sunderland debut in the Capital One Cup against Birmingham City as an injury-disrupted campaign initially quelled his influence, but a strong end to the season saw Jones play a key role in the club's survival and he ended with a total of 18 appearances in all competitions.
