Even though he played a major role in Bath's Heineken Cup victory over Brive in Bordeaux,[2] the hooker was out of favour with England Coach Clive Woodward.
In 1999/2000, Regan re-emerged as a player: he shed over a stone in weight and hit back at critics who believed his line-out throwing was too inconsistent for international level by turning in some impressive performances for Bath.
A prominent figure in the clubs late season challenge for the Allied Dunbar Premiership, he was voted the Bath forward of the year.
Phil Greening's knee and hand injuries allowed him to take over as England's number one hooker for the Six Nations Championship; however, Clive Woodward opted for Leicester Tigers Dorian West and Regan was forced to sit on the bench for most of the campaign.
After moving to Leeds his displays not only saw him become a crowd favourite but also saw a revival in his international career, as he was selected for the England squad for the 2003 Rugby World Cup.
